Emmanuel Goldstein directs the organization 2600 Enterprises, Inc., publishes a magazine called 2600: The Hacker Quarterly (which has associated monthly meet-ups around the world), and hosts the hacker convention Hackers on Planet Earth (HOPE). In 1993, he testified before the United States House of Representatives Subcommittee on Telecommunications. He was questioned in relation to the content of 2600 as part of discussions concerning the Digital Telephony Bill; also known as the Communications Assistance for Law Enforcement Act. He is the host of both the weekly radio programs Off the Hook on WBAI-FM and Off the Wall on WUSB-FM. While Off the Hook often includes a panel of guests and is frequently centered on technological topics, Off the Wall is usually narrated by himself and has covered a wide range of topics. Off the Hook has been on the air since 1988. He directed the 2001 film Freedom Downtime, a documentary about the incarcerations of Kevin Mitnick and Bernie S that also examines alleged distortions in mainstream media coverage of Mitnick's case.
