Time magazine began publishing its weekly issues in March 1923, Roy Larsen was able to increase its circulation by using U.S. radio and movie theaters around the world. It often promoted both Time magazine and U.S. political and corporate interests. According to The March of Time, as early as 1924, Larsen had brought Time into the infant radio business with the broadcast of a 15-minute sustaining quiz show entitled Pop Question which survived until 1925". Then in 1928, Larsen "undertook the weekly broadcast of a 10-minute programme series of brief news summaries, drawn from current issues of Time magazine ... which was originally broadcast over 33 stations throughout the United States". Larsen next arranged for the 30-minute radio program The March of Time to be broadcast over CBS beginning on March 6, 1931.
