U.S. Immigration and Customs Enforcement and Justice Department officials on Wednesday announced that they have shut down nine websites as part of an initiative to bring criminal actions against sites that sell counterfeited goods and pirated movies.

Flanked by unfinished wooden sets on a soundstage at The Walt Disney Co.’s headquarters in Burbank, Calif., officials of ICE plus two studio executives and representatives of two of Hollywood’s largest unions said that thousands of jobs are lost when consumers download pirated movies or television shows from illegal websites.
