  • The Scripps family founded 8MK, which claims that on Aug. 20, 1920, it 'became the first radio station in the world to broadcast regularly scheduled programs.' According to this claim the first broadcast began at 8:15 p.m. from the second floor of The Detroit News Building with the words 'This is 8MK calling,' followed by the playing of two phonograph records, 'Annie Laurie' and 'Roses of Picardy,' a query by an announcer to unseen listeners, 'How do you get it?,' and the playing of taps. The broadcast is thought to have been received in some 30 Detroit homes. The station, then licensed to the Detroit Evening News, says it has been on the air continuously ever since. The newspaper was established in 1873 by James Edmund Scripps, who apparently first became interested in radio in 1902 after listening to a Detroit experimental wireless operator, Thomas E. Clark. James E. Scripps and his only son, William Edmund Scripps, attended a private demonstration of Clark's system of wireless transmission of Morse code and then helped finance Mr. Clark's work. Meanwhile, William John Scripps, known then as 'Little Bill,' son of William E. Scripps, was by 1918, at the age of 13, a devoted ham radio hobbyist. Out of that hobby grew WWJ. It was largely in the Detroit News plant that young Bill did his radio experimenting and it may have been in deference to the boss's son (J. E. Scripps died in 1906), that the newspaper started a radio page which later led to the formation of the newspaper's station. [Source: Broadcasting Magazine, 1970]
