America's three best channels for wasting an evening have all just received Android streaming apps, with limited access to full episodes without any TV subscription necessary on all three.
That's right - you can get full streaming episodes of some shows without providing credentials of any kind, though subscribers of Comcast and DirecTV will receive a larger pool of content to choose from than those who choose not to log in.
I tried out the History Channel app, and everything seems to be in working order. Unfortunately, the selection of shows isn't complete. Even after logging in, the most Top Gear USA content I could get came in the form of episode clips, as opposed to full-length features.
