As has been the case previously, there's no way to know the exact period these rankings for the New York City area from The Pulse, Inc. cover. A December 11th, 1949 article in The New York Times stated only that the rankings come from "the latest report" and list the "major television shows finishing in the following order in the metropolitan area." Here's the list:
1. Texaco Star Theatre (The Milton Berle Show) (WNBT)
2. Arthur Godfrey's Talent Scouts (WCBS)
3. The Goldbergs (WCBS)
4. Arthur Godfrey and Friends (WCBS)
5. Toast of the Town (WCBS)
6. Stop the Music (WJZ-TV)
7. Fireside Theatre (WNBT)
8. Studio One (WCBS)
9. The Philco Television Playhouse (WNBT)
10. Suspense (WCBS)
Note that WCBS easily had the most programs in the Top Ten, although WNBT had the number one program. New York City's ABC station, WJZ-TV, could only place one show in the Top Ten, Stop the Music.
