2600: The Hacker Quarterly is a traditional (printed) magazine named for the fact that phreakers in the 1960s found that the transmission of a 2600-hertz tone (which could be produced perfectly with a plastic toy whistle given away free with Cap'n Crunch cereal - discovered by John Draper) over a long-distance trunk connection gained access to "operator mode" and allowed the user to explore aspects of the telephone system that were not otherwise accessible. The magazine is published by Eric Corley and his company, 2600 Enterprises, Inc., and specializes in publishing technical information on telephone switching systems, satellite descrambling codes, and news about the computer underground.
2600 has established the HOPE (Hackers On Planet Earth) conferences as well as meetings in Argentina, Australia, Austria, Brazil, Canada, Denmark, England, Finland, France, Greece, Ireland, Italy, Mexico, New Zealand, Norway, Poland, Russia, Scotland, South Africa, Sweden, Switzerland, and the United States which take place on the first Friday of the month at 5 pm local time. 2600 Meetings exist as a forum for all interested in technology to meet and talk about events in technology-land, learn, and teach. Meetings are open to anyone of any age or level of expertise.
2600 Films has made a feature length documentary about famed hacker Kevin Mitnick, the Free Kevin movement and the hacker world, entitled Freedom Downtime.
Additionally the 2600 has been involved in many court cases related to technology and freedom of speech alongside the Electronic Frontier Foundation.
