The two openings gave affiliates the option of screening either a fifteen-minute or thirty-minute local newscast preceding Carson. Since 1959, the show had been videotaped earlier the same broadcast day. As more affiliates introduced thirty minutes of local news, Carson's monologue was being seen by fewer people. To rectify this situation, Ed McMahon and Skitch Henderson co-hosted the first fifteen minutes of the show between February 1965 and December 1966 without Carson, who then took over at 11:30. Finally, because he wanted the show to start when he came on, at the beginning of January 1967 Carson insisted the 11:15 segment be eliminated (which, he claimed in a monologue at the time, "no one actually watched except the Armed Forces and four Navajos in Gallup, New Mexico"). By the mid-1970s "Tonight" was the most profitable show on television, making NBC $50 to $60 million ($ to $ million in ) each year. Carson influenced the scheduling of reruns (which typically aired under the title "The Best of Carson") in the mid-1970s and, in 1980, the length of each evening's broadcast, by threatening NBC with, in the first case, moving to another network, and in the latter, retiring altogether. In order to work fewer days each week, Carson began to petition network executives in 1974 that reruns on the weekends be discontinued, in favor of showing them on one or more nights during the week. In response to his demands, NBC created a new comedy/variety series to feed to affiliates on Saturday nights that debuted in October 1975, "Saturday Night Live". In 1980, Carson renewed his contract with the stipulation that the show lose its last half-hour. On the last 90-minute show (September 12, 1980), Carson explained that by going to an hour, the show would feel more fast-paced, and have a greater selection of guests. For a year, Tom Snyder's existing talk show, "Tomorrow", was expanded to 90 minutes and forced to change its format, adding gossip reporter Rona Barrett as a co-host and taking on the name "Tomorrow Coast to Coast". This was short-lived as a year and a half later, Snyder had quit and "Tomorrow Coast to Coast" had been canceled. Carson was given authority to fill the vacant time slot and used it to create "Late Night with David Letterman" (1982–1993). Today, "The Tonight Show" remains one hour in length and is still followed by "Late Night", currently under the title "Late Night with Seth Meyers" (2014-).
