The Wall Street Journal Reported last week that News Corp.'s Twentieth Century Fox has subpoenaed Google Inc.'s YouTube video-sharing site to unveil the identity of a user who uploaded pirated copies of recent episodes of "24" and "The Simpsons."

The subpoena filed Jan. 18 in the U.S. District Court for the Northern District of California requests that YouTube disclose information sufficient to identify the subscriber so that Fox can stop the infringing immediately.
