Others noticed SWTPC success. Forrest Mims, a founder of MITS (Altair 8800), tells about his "Light-Emitting Diodes" cover story (Popular Electronics, November 1970) in an interview with Creative Computing. In March, I sold my first article to Popular Electronics magazine, a feature about light-emitting diodes. At one of our midnight meetings I suggested that we emulate Southwest Technical Products and develop a project article for Popular Electronics. The article would give us free advertising for the kit version of the project, and the magazine would even pay us for the privilege of printing it! The November 1970 issue also has an article by Forrest M. Mims and Henry E. Roberts titled "Assemble an LED Communicator - The Opticon." A kit of parts could be ordered from MITS in Albuquerque, New Mexico. Popular Electronics paid $400 for the article. Merger with Electronics World Radio & Television News became Electronics World in 1959 and in January 1972 was merged into Popular Electronics. The process started in the summer of 1971 with a new editor, Milton S. Snitzer, replacing the longtime editor, Oliver P. Ferrell. The publishers decided to focus on topics with prosperous advertisers, such as CB Radio and audio equipment. Construction projects were no longer the feature articles. They were replaced by new product reviews. The change in editorial direction upset many authors. Dan Meyer wrote a letter in his SWTPC catalog referring to the magazine, Popular Electronics with Electronics World, as "PEEW". He urged his customers to switch to Radio-Electronics. Don Lancaster, Daniel Meyer, Forrest Mims, Ed Roberts, John Simonton and other authors switched to Radio-Electronics. Even Solid State columnist Lou Garner moved to Radio-Electronics for a year. Les Solomon, the Popular Electronics Technical Editor, wrote 6 articles in the rival Radio-Electronics using the pseudonym "B. R. Rogen". In 1972 and 1973 some of the best projects appeared in Radio-Electronics as the new Popular Electronics digested the merger. The upcoming personal computer benefited from this competition between Radio-Electronics and Popular Electronics. In September 1973 Radio-Electronics published Don Lancaster's TV Typewriter, a low cost video display. In July 1974 Radio-Electronics published the Mark-8 Personal Minicomputer based on the Intel 8008 processor. The publishers noted the success of Radio-Electronics and Arthur P. Salsberg took over as Editor in 1974. Salsberg and Technical Editor, Leslie Solomon, brought back the featured construction projects. Popular Electronics needed a computer project so they selected Ed Roberts'
