Radio from the "Mertchandise Mart" centered around the many studios on the 19th floor. Only one studio, Studio F, was on the 20th. Like its Radio City Rockefeller Center counterpart, there were NBC pages (Bob Sirott was one of them in the late 1960s) and a host of staff announcers. In 1947, Hugh Downs ("Today Show" and "20/20"), Garry Moore ("I've Got A Secret") and Durward Kirby ("The Garry Moore Show") were on the WMAQ staff, as was Mike Wallace, later of "60 Minutes" fame. Dave Garroway (1913–1982) also arrived on the NBC airwaves via WMAQ with his "1160 Club" playing big band and jazz music in the 1940s. Garroway was also responsible for organizing a series of local jazz concerts and establishing a Chicago lounge "Jazz Circuit" in 1947 which revived interest in the music genre. In 1948 and 1949, Garroway was voted the nation's top Disk Jockey by his peers in "Billboard's" annual poll. Garroway would eventually host a number of television shows including the "Today Show".
