The show began broadcasting from 10 Rockefeller Plaza in 1952. The studio was on street level with huge windows around which passers-by would gather to appear on TV. After a few years, the show moved to a more traditional studio in 30 Rockefeller Plaza, the worldwide headquarters of NBC. In 1994, the show relocated to that same glass-enclosed studio, 1-A.
When the show started in 1952, it was seen only in the Eastern and Central time zones, broadcasting three hours a morning but seen for only two hours in each time zone. Later, it aired live for five hours a morning, but it was seen for only two hours in each time zone. Since 1958, the show is tape-delayed for the different time zones. For many years it was a two-hour program from seven to nine ET, until NBC expanded it to three hours (7-10 A.M. Eastern Time/Pacific Time; 6-9 A.M. Central Time/Mountain Time) on October 2, 2000. In 2007, NBC expanded the show to four hours.
The teen audience members used for this segment were all members of the Spring Awakening street team, and this is how they were chosen.
