Last October, YouTube TV started working as a cable login, allowing subscribers to the service to access other participating networks' streaming sites and apps with their YouTube credentials. However, at the time, we didn't have an exhaustive list of all the networks that support the feature. Now, Google has published it and we know there are 67 partner sites (though with several regional iterations of the same one).

If you want to check these out, head to the support page linked below, find the network you're interested in, and follow its link. When asked to log in, you'll be able to choose YouTube TV as your provider and then enter your credentials to get access. This also works on the networks' Android apps, if you'd rather consume your TV there instead of a website.
