OTD in 1927, the Columbia Phonograph Broadcasting System began supplying 16 radio stations with programming. The network soon had financial problems and was sold to William Paley (whose father ran a cigar company that was a key advertiser). In January 1929, it was reborn as @CBS. https://t.co/1q3QfD0J59 — PolitiTweet.org
