If you’re on Twitter, join the #CaptionTHIS protest tomorrow. People will be tweeting at TV networks and web video producers using that hashtag, in an effort to convince them to make their programming accessible.
I’m already planning on tweeting @NickelodeonTV, for instance. The main reason I’ve been posting captioning rips from Legend of Korra is because, if you require captions, there is no place to watch the show online and be able to follow the dialogue. Amazon? iTunes? Nickelodeon’s own web site? Not one of them includes the captions that the show was broadcast with.
More information on the movement is in this YouTube video. Which, naturally, is captioned— and, in fact, is also silent. (For screen-reader users, there’s a full transcript included in the description at YouTube.)

I’m not on Twitter… it’s probably too late, but signal boost anyway!
