File-sharing services defend distribution

LOS ANGELES (AP) -- Lawyers representing record companies and movie studios argued in federal court that companies that market file-sharing services encourage illegal copying of music and movies.
Lawyers for the sharing services said they can't control what users do with their software.
The arguments were made in a hearing Monday seeking summary judgment in a lawsuit against the popular file-sharing services Grokster, Kazaa and StreamCast, which distributes the Morpheus peer-to-peer software. It is similar to previous cases in which courts essentially shut down the file-sharing services Napster and Aimster.
Both sides are seeking summary judgment.
