The Motion Picture Association of America on Thursday sued Pullmylink.com, a Web site featuring links to free movies and TV shows, claiming the site promotes and profits from copyright infringement.

The lawsuit, filed in Los Angeles federal court.

The campaign against sites that link to, but do not host, illegal content has raised some eyebrows with critics asking why the association doesn't go after the host sites or Internet search engines such as Google.com , which owns video sharing site YouTube.com.

"Pullmylink.com and sites like it are a one-stop shop for copyright infringement. We have filed several other similar suits and will continue to do so in order to hold operators accountable for their illegal activities. Profiting from the theft of other people?s creative works is illegal and we have every intention of shutting this, and sites like it, down for good," said John Malcolm, Executive Vice President and Director of Worldwide Anti-Piracy Operations for the MPAA.

MPAA's complete announcement is available here.

The MPAA, which represents Hollywood's major studios in government affairs, has obtained settlements or resolutions in the six other cases against Web aggregators of video content.

Pullmylink.com sees 12,000 visitors a day who view more than 39,000 pages of content, including movies that are still in theaters and cable television shows.
