The best free TV-streaming services that don’t require you to sign in

[FOX] Without a sign-in, you can watch the latest five episodes of current shows, and new episodes of returning shows unlock eight days after airing on TV. However, the Fox site imposes a “Preview Pass” that limits you to one hour of free viewing (though not commercial-free). After that, it appears that you’ll need a sign-in if you want to continue watching in your browser. The mobile apps don’t seem to have that limitation. – Rick Broida, CNET
