Stephen Colbert's "Colbert Report" has posted two videos about SOPA. The first video "explains" what SOPA is about. The second video contains an interview with Danny Goldberg (a music industry supporter) and Jonathan Zittrain (a Harvard law professor). Techdirt has a discussion of these videos.
In the first video, don't miss the Mickey Mouse doll with an anti-infringement slogan. And the fact that the FBI admits that its estimate of the dollar amount lost to piracy has no factual support. In the second video, don't miss Colbert's and Zittrain's debate about whether Justin Bieber should go to jail. (They seem to agree that he should, but for different reasons.)
