If there's one thing streaming video watchers love, it's free stuff. So it wasn't a huge surprise to see Roku launch a free ad-supported movie channel of its own last year. Now, it's adding news coverage to that selection, starting with ABC News Live, a 24/7 online offering and an offering that can compete with CBS' own online-only news channel. And on top of that, there will also be live streams from Cheddar, People TV and Newsy. Sure, it may seem like what's old is new again, but it's a smart move for Roku, since it makes its streaming platform much more useful for consumers. And more importantly, it gives them one more reason to stick around.
