This Week in Rock History
1973 – KISS make their stage debut, performing at the Coventry Club in Queens, New York.
1969 – The Beatles perform in public for the last time, an impromptu, traffic-stopping lunchtime concert on the roof of Apple's Saville Row offices in London that's filmed for Let It Be.
1949 – Spurred by Columbia Records' new 33-1/3 rpm LP format, rival RCA-Victor introduces the 7" 45 rpm single and a compact new machine to play it on—the death knell of the 78 record. The vinyl single will dominate records and radio until the advent of the CD in the '80s.
1954 – After losing an acrimonious patent fight with employer RCA, Edwin Howard Armstrong, inventor of FM radio, leaps from his 13th floor New York City apartment. His widow Marian—former secretary to RCA chief David Sarnoff—renews the FM patent battle with RCA, eventually prevailing in 1967. The hi-fi stereo signal of Armstrong's broadcast format quickly revolutionizes rock radio.
