Roku has always been one of our favorite ways to cast content to our televisions, and with good reason: itâs sleek, simple, affordable, and reliable. But one of our favorite things about Roku has nothing to do with its casting ability. Rokuâs wide selection of âchannelsâ (their version of apps) gives you the power to customize your Roku experience and greatly expand what the device can do.Thatâs even more true when you learn about one of Rokuâs best-kept secrets: private channels. When you use Rokuâs remote to click to the channel store, youâre only seeing part of the story. Other channels, like new apps that are still in Beta, wonât be seen there. Thereâs a whole other world of private channels for you to explore!Weâve already shown you how to get private channels on your Roku. Now, weâre giving you the scoop on the channels themselves. Here are our favorite private channels for the Roku.Goats LiveCode: GoatsLiveGoats Live is a webcam feed that is focused entirely on a group of goats. You might not think that this would be fascinating, but you would be very wrong. You need more goats in your life. Download Goats Live and watch some goats, or put it on in the background at your next party. Everyone will want to know where you got this cool goats feed. The live stream goes down from time to time, but in that event you can still meet your goat watching quota with the pre-recorded videos that are also available on the app.iTunes PodcastsCode: ITPCThis great channel aggregates all of the free iTunes podcasts and lets you stream them on your Roku. Youâll get both audio and video podcasts, and the latter are great to watch on your big screen! This app was developed by TheEndless.Nowhere ArchiveCode: NMJS5You probably already know about The Internet Archive, a site with a massive collection of public domain material, including books, software, music, and movies. What you may not know is that you can get the archiveâs entertainment options up onto your big screen with this private channel, which is available through The Nowhere Man.Nowhere TVCode: H9DWCThe Nowhere Manâs best-known private channel is more of a multi-channel, with content from all different places. Some of it is pretty awesome (Adult Swim!) and some of it is pretty lame (looking at you, C-SPAN), but all of it is in one place.Silent Movie ChannelCode: ROLLEMThe public domain is a wonderful thing. The Silent Movie Channel shows really old movies from (of course) the silent movie era. Sometimes some of the options are unavailable, but for the most part the channel works pretty well – and since everything is free, you canât beat the price.Space Time FreeCode: CN6MRTGNASAâs private channel has gone legit, but free space videos are still a popular choice for private channels. Space Time Free is probably the best space-related channel left out in the private section. It draws its video content from multiple space agencies, not just NASA.Video and TV CastCode: LHVDGPVideo and TV Cast turns your Roku into a casting device for local content. That means that you can have your videos saved to your computer and watch them on your big screen, without having to switch the input away from your Roku. This app is convenient, simple, and functional. Check it out at http://video-tv-cast.com/roku/.
