NBC and Fox News Channel sued video-sharing service Redlasso for copyright infringement on Wednesday. They accuse the Web site of showing programs like "The Tonight Show" without permission.
The lawsuit comes two months after the TV networks wrote to the privately held site asking it to stop running unauthorized clips and programs. The lawsuit charges, "Redlasso did not stop
reproducing or publicly displaying the network's content."
The nets are seeking a court injunction and monetary damages.
