I’m watching the #RNC speeches on YouTube. (Like any Internet romantic, I don’t have cable.)
Anyway… Youtube.com/politics is impressive. They have a menu with major news organizations (not just major TV networks), and you can choose to watch coverage from any of them. They even show a lil’ “live” indicator next to the networks who have a livestream related to politics right now.
(The live tweets filtered-per-org are cool, too.)
