TEL (Telephone Electronics Line) was a small publication that was dedicated to phone phreaking and hacking. It began publishing in November 1974. TEL was similar to TAP newsletter but was geared totally toward phone phreaking. In 1975, Pacific Telephone & Telegraph won a lawsuit against the publishers of TEL. The Superior Court of California, County L.A. court ordered TEL to stop publishing immediately. A letter was mailed to all subscribers advising them to destroy all back issues of TEL. TEL ceased publishing after only 7 issues.
