AT&T’s new WatchTV streaming service — which costs just $15 per month, $20 less than the company’s DirecTV Now subscription — is now available on iOS, Android, Chromecast, Apple TV, and Fire TV devices, as spotted by Apple Insider.

WatchTV includes 31 channels as of now, including Cartoon Network, CNN, TBS, TNT, TCM, A&E, AMC, and HGTV. An additional six Viacom channels — BET, Comedy Central, MTV 2, Nicktoons, TeenNick, and VH1 — are promised for sometime in the future, too. Customers will also get access to 15,000 movies and TV show episodes on demand through the service.

WatchTV was announced just days after AT&T completed its acquisition of Time Warner — coincidentally, many of the channels available are Time Warner networks, likely a hint of the kind of corporate synergy that AT&T hopes to be able to put into play with the vast new networks it now owns.

WatchTV is included for free with AT&T’s latest unlimited plans: Unlimited &More and Unlimited &More Premium, but you’ll also be able to subscribe for $15 per month without being on AT&T’s cell plans.
