Common Confusion in Home Theater: Part 9

3d1Today’s blog post is another excerpt from Home Theater for the Internet Age and covers more topics that often confuse both new and old hi-fi and home theater fans alike: Ethernet (hard wired, high-bandwidth computer and hi-fi gear networking), separates, and the role of a broadband internet router in a modern home theater.

The internet router is especially important for those who enjoy streaming media (like Pandora, Spotify, Netflix, and Hulu Plus) and have multiple mobile devices sucking down wi-fi.

Ethernet

From Chapter 3: Components

Ethernet is a standard for connecting computers and home theater components to your home network. Unlike wi-fi, which is a wireless communications standard, it is a wired scheme that operates over special cabling. Like its cousin wi-fi, Ethernet enables audio and video to be streamed from the internet or a part of your network to your home theater. In terms of audio and video components (specifically receivers, Blu-ray players, and streaming media boxes), Ethernet is a valuable feature that provides a better connection than wi-fi, but may involve more expensive installation of cabling in your home. (For more info, see the Ethernet section of the Connection Types chapter.)

ethernet-cablePersonally, I’d seriously consider skipping components that lack Ethernet. Why? Simply because it’s the best way to connect the pieces of your home theater to your local network and the internet, especially for streaming high-definition video. The media formats of today—and tomorrow—all flow more smoothly when transported via Ethernet instead of interference-prone wi-fi.

From Chapter 5: Connection Types

As you learned in the Components chapter, Ethernet is a wired connection technology from the computer networking world that is used in other types of components, such as home theater and home automation equipment. It supports relatively high speeds, has been around for decades, and is very reliable. Many, but not all, receivers and all major streaming media boxes feature Ethernet ports. This connectivity standard operates over special cabling called CAT5 and CAT6 (the current and most robust standard) and can reach lengths of more than 300 feet (100 meters).

Sometimes labeled “LAN” on a device’s back panel, Ethernet isn’t only reliable, it’s the fastest connection available. In a typical home network, Ethernet is roughly two to 20 times faster than wi-fi (when measuring real-world data throughput)! Although most components don’t take advantage of this speed, future standards—like true 4K video—will benefit from it. Another superiority over wi-fi is the lack of sensitivity to radio interference (such as from cordless phones and microwaves). In addition, Ethernet is much less prone to hacking or unwanted eavesdropping than wi-fi. Ethernet is simply the best connection option for computers and home theater equipment.

In most homes, wi-fi is obviously used by all mobile devices (iPod Touches, smartphones, tablets, and laptops). But your receiver never moves, so it doesn’t need the mobile flexibility provided by wi-fi. It does, however, need a fast, solid internet connection—and especially benefits from one that’s much more immune to interference and several magnitudes faster than its wi-fi cousin (helpful when streaming high resolution audio or video without interruptions or buffering).

For these reasons, I decided to connect my receiver and other home theater components to my home network (and the internet) using Ethernet. Because my components aren’t consuming wi-fi bandwidth, they aren’t competing with the mobile devices in my home. If you’ve already gone to the installation expense or invested DIY time to run CAT6 cable from your home’s internet router to your home theater components, there’s no reason to not supply Ethernet to all of your devices.

Splitting Ethernet with a Switch

Sharing a single cable drop with multiple home theater components can be done easily and inexpensively using an Ethernet switch. Similar to a USB hub, this device simply splits and manages the incoming Ethernet signal from a single cable into multiple feeds (some switches provide five ports, while others offer eight or more). There are a few speed standards supported by Ethernet switches. It’s recommended that you get the fastest possible switch to help future-proof your system. This would be a gigabit switch, which is very affordable, with entry-level models costing only about $35. With even higher definition TV right around the corner, data consumption will only increase exponentially.

ethernet switchA friend of mine was recently shopping for a receiver. He had been plugging his cable box and Blu-ray player directly into his TV. He purchased a Chromecast dongle, but his TV features only two HDMI ports, both of which were occupied. Thus, he was forced to purchase a receiver to accommodate his three HDMI inputs (of course, he’s pumping much better sound to his speakers in the process). Instead of paying more for a receiver that featured wi-fi—he was on a tight budget—we simply ensured that the receiver had an Ethernet port. This allowed him to save $120 by purchasing a model lacking wi-fi—while at the same time delivering a considerably faster and more reliable internet connection to his receiver.

For non-mobile devices and when practical, always choose Ethernet over wi-fi.

Separates

From Chapter 3: Components

One thing this book doesn’t deal with in detail is what in the audiophile world is called separates. These are specialty components that handle specific tasks within your home theater, primarily multichannel amplification or surround processing. These are both tasks assumed by a standard AV receiver, although typically—by audiophile standards—at a lower quality level than can be delivered by separates.

It’s hard to argue with the benefit of different power supplies and avoiding any electrical crossover or interference between separate components. It is, in both theory and actual listening reality, an approach that’s superior to that of integrated receivers. But, as with all areas of life, common sense should prevail. There are poor examples of separates on the market, as well as integrated receivers that produce incredible sound and video with robust power (and better value).

As you might guess, separates can get alarmingly expensive. If you want to research separates on your own, check out Anthem, Bryston, Classé, Emotiva, Integra, Marantz, NAD, Parasound, and Rotel. With the exception of Emotiva and (sometimes) NAD, get ready for sticker shock. Even Yamaha joined the game in 2014 with a $6,000 pre-processor and power amplifier pair.

If I was buying separates today, I’d probably go with Rotel, NAD, or Emotiva. I like Rotel’s Class D digital amps and its reputation for clean, refined audio with a wide soundstage. I love NAD’s understated grey matte finish and its legacy for audiophile-quality sound at all volume levels. I also enjoy Emotiva’s engineering philosophy and how the company throws tons of watts at its separates (although other companies offer classier, more refined component styling). The company’s wattage-per-dollar ratio is off the charts. Unlike most separates manufacturers, Emotiva’s prices won’t motivate your spouse to begin Googling ways to kill you in your sleep.

Broadband Internet Router

From Chapter 3: Components

I know, I know, this is a book about home theater, not computers. But with so many streaming services delivered to your home theater via the internet, having a weak router can be more frustration than pleasure. Dropouts when listening to streaming music and freezes for buffering while watching internet video aren’t any fun (somewhat destroying the suspension of disbelief during engaging movies). While problems like this can’t be completely avoided due to internet traffic and server hiccups (issues completely outside your control), they can sometimes be dramatically decreased with a good dual-band router.

Think of a high-end router as serving the role of an internet traffic cop who not only likes to increase the speed limit, but also optimizes your network for the increasingly media-based data pulled down by your increasingly device-filled household.

Wi-Fi Everywhere

Not convinced of the importance of wi-fi in your home? Consider that Roku uses wi-fi even in its remote controls, while Nest sells a wi-fi-enabled smoke detector to complement its wi-fi-based smart thermostat. There are even various models of door locks and LED light bulbs on the market that require wi-fi to configure and operate. From your display panel and AV receiver to your laptop or your child’s iPod Touch, the quality and reliability of your wi-fi connection has never been so important, affecting every member of your family—and even your guests who bring their own mobile devices.

netgear nighthawk r700Better router models provide several advantages, including stronger amplifiers and dedicated antennas to enhance signal strength, range, and overall data speed. Consider that YouTube and Netflix together make up more than 55% of the overall volume of data consumed on the internet. In other words, most of the data streamed online is video—and sometimes HD video in Dolby Digital surround sound. This video consumes a lot of bandwidth, more than any other type of data on your network or the internet.

Also consider that this data isn’t consumed in short bursts, like traditional computer-based internet use involving a web browser or mobile apps for social networks like Facebook, Twitter, or Instagram. Watching a two-and-a-half hour movie on Netflix or Apple TV requires not only good bandwidth, but a data stream that’s consistently reliable. Now recognize that there might be two, or even three, simultaneous video streams from the internet entering your home at certain times of the day (such as after school or work, during the evening, or on weekends). This is when most readers begin to understand the sheer volume of media streaming that occurs in their home and the pivotal role played by their wi-fi router.

When you sign up for internet service, there’s a good chance that your ISP, or internet service provider, will provide you a combination modem/router that includes basic wi-fi capabilities. This is the device that is both bringing the internet into your home via coaxial, twisted pair (telephone), or fiber optic cabling and then, as a second step, wirelessly broadcasting it to your home via a wi-fi signal. Any internet-connected device in your home relies on your router for the upload and download of all data.

The Free One Sucks

For companies like AT&T, Cox, Comcast, and Time Warner to make money, they obviously must keep overhead as low as possible. This means that the modem/wi-fi router box they provide with their ISP accounts isn’t the best available. Not by a long shot. Regardless of the inherent quality of these freebies, they aren’t giving you the best experience possible. With so many mobile and home theater devices in your home demanding a robust and full-time wi-fi connection—and typically streaming bandwidth-hungry audio or video—the role of your router is more important than ever.

Buy Dual Band

First, be sure to purchase a wi-fi router that’s dual-band. This will include support for both 2.4 GHz and 5 GHz devices, essentially putting them on different networks and boosting the bandwidth provided to all devices by helping prevent bottlenecks and streamlining data flows.

A benefit of a dual-band router is that you’re guaranteed to have the latest wi-fi standard, 802.11ac (sometimes called gigabit wi-fi). This gives you the fastest wireless connectivity, helping provide the best possible performance, especially with new devices that enter your household that probably support this standard. Routers from ASUS, Cisco, D-link, Linksys, and Netgear are recommended because of their quality, affordability, and long track records with consumers and enterprises.

Buying the best router possible for your home in 2014 is a $130-$280 endeavor. Check out the $200 Netgear Nighthawk R7000 (my personal pick and a PC Magazine’s Editors’ Choice, pictured above), the $130 ASUS RT-N65U or $220 RT-AC68U, or the $230 Linksys EA6900 (another PC Magazine Editors’ Choice recipient). Also consider the top-shelf $280 Linksys WRT1900AC. Another nice contender is the $175 TRENDnet TEW-818DRU (street prices will typically be lower on most models). Not chump change, but by the end of the operation you’ll know you have the fastest, most reliable, and most manageable wi-fi on the block.

Streaming Media Stick Wars

3d1It began in August 2013 when Google introduced the Chromecast. A small, Rubenesque HDMI dongle that allows you to stream music and video to your TV or home theater, the $35 Chromecast was an instant hit. This groovy petite player allows popular media services like Pandora, YouTube, and Netflix to easily be sent to your home theater from any Android or Apple smartphone or tablet—and even laptops and desktop computers.

Then, in the spring of 2014, Roku introduced the $49 Streaming Stick, a slick little purple dongle that, like Chromecast, plugs into a TV or AV receiver’s HDMI port to bring you music and video streaming from the internet. Roku likes to tout how its dongle is “perfect for wall mounted TVs”; as are all of these svelt mini-streamers. Although slightly more expensive than its competition from Google, Roku’s streaming stick offers a dedicated remote control and so many more channels it isn’t even funny (like, um, 1,700 more, something Roku fans love).

Recently, the market for these mini-streamers got more crowded when Amazon announced the Fire TV Stick, the $39 dongle that falls between Chromecast and Roku in terms of price. Like Roku’s Streaming Stick, it features a nice, ergonomic remote. Unlike its competitors, Amazon sells a $40 game controller for the Fire TV Stick that allows you to play more than 200 different games. If you’re a casual gamer (as opposed to someone who needs an Xbox or Playstation to engage in their favorite first-person shoot out), the Fire TV Stick, with optional game controller, is a unique solution. It’s also pretty much the least expensive way—at $70 total—to get gaming into your living room.

rock streaming stickFor the most part, these inexpensive media streaming devices are more similar than different. They all plug into HDMI ports and require a dedicated power supply (they can’t get their juice from the HDMI port), so you’ll need a spare outlet around your TV or home theater gear. They all use wi-fi to ride on your broadband connection and suck down their audio or video stream from the internet. And they all offer major streaming services like Netflix, Hulu Plus, YouTube, and a handful of streaming music services.

One thing all three of these streaming dongles have in common is being the little brothers to full-fledged “set-top box” media streamers from each company. Google’s new Nexus Player, the Roku 3, and Amazon Fire TV, all priced at $99, take streaming media to the next level, offering more robust features and functionality. Apple is the standout in offering a similar ($99) set-top streamer called Apple TV, but no HDMI dongle variant. One of the biggest advantages of these full-fledged media streamers—with the glaring and inexcusable exception of Google’s new Nexus Player—is their ability to connect to your home network and the internet via Ethernet hard cabling, eliminating the interference and connectivity problems inherent in wi-fi.

Google’s Chromecast is the odd man out in terms of bundling no dedicated remote. Not that there isn’t one: It’s your mobile device. Because this trend-setting device is platform agnostic, it matters not if you use an iPhone, Android smartphone, Samsung tablet, or the venerable iPad. Any Android or Apple smartphone or tablet works with Chromecast.

chromecastBut let’s be realistic, it’s all about the content. As sexy as the candy wrapper might be, what we really care about is the chocolate. Roku’s Streaming Stick offers all 1,800+ channels that its more robust sibling Roku devices deliver. This is, hands down, the largest selection of content offered by any company selling streaming devices. If you’re one of those consumers who blows away the average four hours of television programming consumption per day and desires the largest availability of channels possible: Stop reading this, look up the Roku Streaming Stick on Amazon, and click Add to Cart.

However, this plethora of channels isn’t all peaches and cream. Roku’s lineup offers hundreds of arguably crappy and often obscure channels, many of which are foreign language-based. According to PC Magazine’s review, “…individual channels are still a mish-mash and many aren’t integrated into the search feature, so you have to wade through a lot of things you might not want.” However, Roku wins the agnostic award for not twisting your arm to rent or purchase content from a particular ecosystem, unlike Amazon’s Fire TV Stick.

Speaking of the Fire TV Stick: This newcomer is perfect if you’re a subscriber to Amazon Prime and love to get your entertainment from Prime Instant Video. Like Apple TV, both Apple and Amazon do their best to push you into their respective iTunes and Prime Instant Video ecosystems.

fire tv stickGoogle’s Chromecast differs in terms of channel availability. Instead of serving up a canned set of channels, Google has created a platform on which other media streaming services can jump in if they choose. Thus, the Netflix and Hulu Plus mobile apps have been updated to support Chromecast. When running these apps, you simply tap the Chromecast icon and, voila, you’re watching it on your TV or home theater. The only problem—especially compared to Roku and Amazon—is that only about 35 streaming apps currently support Chromecast. However, if you’re like my cord cutting family and consume most of your entertainment from Netflix, Hulu Plus, Crackle, and Pandora, these major services all support Chromecast (in addition to Watch ESPN, HBO GO, Songza for music, Vevo for music videos, and, of course, iTunes wannabe Google Play Movies & TV).

So there you have it. Unfortunately, the game-friendly Fire TV Stick won’t be available until January 2015, so forget Santa leaving you one in your stocking (smooth timing, Amazon; what are you smoking out there in Seattle?). It’s nice to see the market for uber-affordable streaming media devices getting competitive and catering to different entertainment ecosystems.

And it’s only going to get better.

Apple TV: Best Media Streamer?

3d1[Updated August 6, 2015]

The market for streaming media devices has, quite favorably, become somewhat crowded in the past year. Apple TV, Roku’s lineup, Amazon Fire TV, Chromecast, and Google’s new Nexus Player all vie for the dollars of both cord cutters and cable subscribers alike.

Macworld UK reviewed the now $69 Apple TV in the summer of 2014. It’s biggest criticism: “Not much content.” When I first purchased my two Apple TV units in the spring of 2013, the service offered roughly 25 streaming services—some requiring subscriptions (like Netflix and Hulu Plus), some requiring a cable or satellite TV account (the Disney channels, for example), and some free (Sony’s ad-supported Crackle, among others).

Today, Apple TV offers 74 channels—including Google’s YouTube, Vimeo, the new HBO NOW, and more specialized stuff like Bloomberg TV for financial news, Vevo for music videos, and even Yahoo’s Flickr for crowdsourced photos (which can even serve as a source for Apple TV’s screen saver, a very groovy feature indeed).

If you don’t own an Apple TV, but checked out the channel lineup a year or two ago, you’ll be pleased to know that it now provides several channels from mainstream TV that were previously absent. These include ABC, CNBC, Smithsonian Channel, Fox Now, and Britain’s Sky News—all of which require no cable/sat TV subscription (but you’re also getting canned episodes and segments, not a live stream). Many channels, however, require old school TV service and a login to watch on Apple’s venerable streaming box. These include Disney’s multiple offerings, PBS and PBS Kids, FX Now (famous for featuring every episode of The Simpsons), reality-leaning A&E, and grandpa’s favorite, the History channel.

There’s also access to top-tier “premium” services from the cable/sat TV world, including HBO GO, Showtime Anytime, and Disney’s ESPN. Even with basic cable, these avenues for high-quality entertainment will serve only to taunt you from Apple TV’s navigation menu. Slowly, but surely—in its own very purposeful fashion—Apple continues to offer more channels and expand the offerings of its industry-leading set-top streamer.

And then there’s the other big ecosystem-driven box: Amazon Fire TV. Like Apple’s offering, this same-price ($99) media streamer caters to people who subscribe to Amazon Prime and utilize the company’s Prime Instant Video (one of the best options for folks who don’t want Netflix, or to supplement it, and have no desire to watch stuff from iTunes). Fire TV offers some features absent from Apple TV, like a more intelligent remote, but also continually pushes users into Amazon’s ecosystem for rentals and purchases of music, movies, and TV episodes.

apple tv for blogRoku’s various streaming devices—it sells four (priced at $49-99); more than any competitor—are the agnostic “do everything” media muscle residing in the middle. Roku’s website legitimately boasts “Over 1000 more channels than Amazon Fire TV, Apple TV, or Chromecast.” Roku has definitely differentiated itself from Apple’s minimalist channel lineup. For those who watch a ton of TV (especially cord cutters) and want the widest selection of channels available—including a boatload of obscure, arguably crappy, and fringy foreign language programming—Roku is the hands-down winner in the streaming media box wars.

One of the most appealing features of Apple TV is support for AirPlay, Apple’s wi-fi-enabled media casting tech. Built into all of the company’s mobile gadgets and computers, AirPlay allows you to send music and video to your TV or home theater with the tap of an icon (said CNET in August: “AirPlay is just awesome”). Some AV receivers, like many from Yamaha, Denon, and Pioneer Elite, already have AirPlay built into them. For most consumers, however, Apple TV is a great way to AirPlay-enable your display panel and surround sound speakers. But, again, this will be appealing only for those with multiple iOS and OS X devices already in use.

And let’s not forget Apple TV’s slim and sleek aluminum remote control. While it might sound trivial, the remote is a critical element of any media streamer. It’s the part you touch, toss on the ottoman, and sometimes curse. But Apple has some work to do in this department. Its remote supports only infrared (IR; a beam of light), not a radio frequency like Bluetooth or wi-fi. This means you have to point it at the small black Apple TV puck sitting next to your TV or AV receiver. This is a huge pain for many, like me, who have a TV mounted on a wall opposite their home theater gear and must point the remote behind them. Both the top shelf Roku 3 and Amazon Fire TV feature radio frequency-based remotes. Unlike Fire TV’s offering, the Apple TV remote also doesn’t support voice navigation and search.

roku 3The “match” between a consumer’s lifestyle or preferences and a media streaming device should depend most on one’s existing (or planned) digital ecosystem. If you have several of Apple’s iOS mobile devices floating around your home, Apple TV makes sense. If you don’t—and enjoy Amazon’s Prime Instant Video, for example—it probably doesn’t. Apple is obviously catering to its huge installed base of tablets, smartphones, and computers.

Who gains the most from Apple TV? Consumers who use iTunes to consume music, movies, and TV episodes, people who love to groove to Beats Music for on-demand songs or enjoy iTunes Radio for Pandora-like music discovery, and those who can’t do without their beloved iPads, iPhones, and other iDevices.

Quite honestly, those who simply suck down tons of Netflix and Hulu Plus, and own few or no Apple devices, can gain equal benefit from nearly any streaming media box. Personally, I’d recommend the Roku 3, unless you’re really into Amazon’s ecosystem and you’re a lightweight gamer, in which case the Fire TV is probably most appealing.

Don’t make the mistake of pigeonholing Apple TV into a corner appropriate only for fanboys. I’m an Apple fan, but not a fanboy. With two iPads, a Mac Mini, and several iPod Touches floating around my house, Apple TV simply works. The intuitive navigation, slick interface, and Apple’s minimalistic DNA shine through. If you’re a fan of Apple’s design and approach to all things digital, you’ll feel right at home with this premium media streaming device.

Home Theater Basics

3d1The following is an excerpt from Chapter 2: Home Theater Basics from my new book Home Theater for the Internet Age. This book isn’t for audiophiles or videophiles. If you’re an average middle class person who doesn’t know much about this topic, you outnumber the “experts” and home theater nerds by about 10,000 to 1.

I’ve always enjoyed helping people understand and embrace modern technology. In the case of home theater, this tech can bring together families in front of a big display panel for a new movie release on a shiny little disc—or, increasingly, streamed from the internet. You can enjoy family photos, MP3 songs, or home videos stored on a computer that resides nearly anywhere on your wi-fi network. All using nothing more than a decent Blu-ray player (playing discs covers only one-third the functionality of modern Blu-ray players, as you can learn here).

If nothing else, please understand that you can enjoy full surround sound, high-definition video, and all the glory of modern home theater on any budget. The most common misperception of home theater is that it’s too expensive and you can’t afford it.

But you can. Trust me.

As consumers, we’re in the middle of multiple transition periods within the home electronics and entertainment industries. These changes are in the form of rapid advances in both hardware and services. It’s no longer uncommon for one to have a 60-inch display panel hanging in their living room, to be one of the 50 million people who watch movies and TV shows on Netflix, or to be among the 76 million consumers who listen to music on Pandora each month. These don’t constitute early adopter status in today’s world of home entertainment.

Since Apple introduced its iconic iPod line of portable music players in 2001, the human race has been slowly transitioning from entertaining itself by purchasing physical media, like optical discs, to instead downloading songs from iTunes or streaming movies or TV from services like Hulu or Vudu. Today the average consumer has more home entertainment options than ever—along with a more detailed and potentially confusing array of technologies and media sources.

What Defines Home Theater?

Let’s define a few things. First, a home theater isn’t mobile. It’s not a laptop with a set of headphones (even if the laptop features a Blu-ray player). Home theater is four basic components:

  • Display panel
  • Audio/video receiver
  • Blu-ray player
  • Five+ specialized speakers

These are the elements necessary for full-on home theater and how it’s defined in this book. Anything short of these elements doesn’t cut it in terms of home “theater.” While it could be argued that a set top box for bringing audio and video content into your home theater is a necessity, some cord cutters are perfectly happy with physical discs from Redbox, the Neflix disc-by-mail service, or a local video store.

One of the most common configurations for consuming TV programming and movies is a display panel TV with two input devices: A Blu-ray player and a cable/satellite set-top box (using only the speakers on the TV). Maybe there’s a game console or DVR thrown in the mix. But this also isn’t home theater (where’s the audio/video receiver and rear surround speakers?).

Connecting Components

In the past, the task of connecting home theater components was confusing. Different components connected with different standards and there were separate connections for audio and video. For the layperson, connecting components was a headache and typically resulted in either a frustratingly botched job, professional installation (planned or unplanned), or scouring web-based forums desperately seeking help from others. Today it’s different. Now it’s all a single standard that transports both audio and video, and does it in Blu-ray-quality high definition: HDMI. Say it with me: H-D-M-I. It’s all you need to know.

Surround Sound

In terms of audio, the difference between a “stereo system” and a “home theater” is surround sound, which has been relatively common for well over a decade. Without a collection of surround sound speakers, home theater can’t exist. Today, a significant portion of broadcast and cable TV programming—and nearly all movies produced in the past decade—are delivered with a six-channel or greater audio mix that requires a surround speaker configuration and compatible audio/video receiver to be fully appreciated.

Discrete Channels

Surround sound isn’t just about adding more speakers in your living room. It’s about discrete channels of audio information coming from specific locations within your listening environment. In other words, the producers of a TV show or movie can purposefully make, say, the voices of the characters come from the speaker directly below your TV, where they’ll be the most realistic.

Meanwhile, background noises—such as barking dogs, slamming doors, and guns firing—can be directed to the rear speakers. The ability of content producers to utilize between five and twelve speakers in your living room, in a predictable arrangement, is why affordable home theater systems now rival the experience of going to a movie theater (and why commercial theater chains have to install football field-size screens with vibrating chairs just to get our attention).

Content Services

Content services that deliver streaming audio, video, and even games to your living room home theater have proliferated like crazy during the past few years. What’s interesting is that most people have labeled this the evolution of the internet, not home theater.

It’s all convoluted today, part computer and part stereo system. We’re in the middle of the convergence of computing/internet technologies and the hardware, software, and standards on which video and audio are affordably reproduced in the home. Home theater simply does not live up to its potential without the internet and broadband connectivity. Netflix, YouTube, HBO Now, Pandora, Hulu Plus, Spotify, iTunes, and other internet-based services offer more content than you can ever consume. While your local liquor store might not sell you bourbon on Sunday, online streaming services are available on-demand, 24 hours a day, seven days a week.
