  Broadcasting milestones
  The Tonight Show began its broadcast at 11:15 p.m. ET, following an affiliate's 15-minute news broadcast. As more affiliates lengthened their local news programs to 30 minutes, the show began doing two openings, one for the affiliates that began at 11:15 and another for those who joined at 11:30. By early 1965, only 43 of the 190 affiliated stations carried the entire show. After February 1965, Johnny Carson refused to appear until 11:30, and Ed McMahon "hosted" the 11:15 segment. Carson was not happy with this arrangement since McMahon's monologue covered the same ground as Carson's, and he finally insisted that the show's start time be changed to 11:30. As a result, the two-opening practice was eliminated in December 1966.
  When the show began it was broadcast live. On January 12, 1959, the show began to be videotaped for broadcast later on the same day, although initially the Thursday night programs were kept live. Color broadcasts began on September 19, 1960.
