If one wants to quibble with Cushman's television history... The (television version) of the infamous Amos 'n Andy actually beat Lucy and Desi to the air by four months (June 21, 1951 vs. October 15, 1951). Andy filmed at Hal Roach Studios (in Culver City) using the three-camera method. The claim about The Lone Ranger is mostly right. Hopalong Cassidy actually beat that series to the air, but Hopalong Cassidy was made of repurposed theatrical shorts until 1952, when it began filming new material.
