McKay also had a WCBS connection and it's the reason his last name was changed, according to NPR:
McKay was born Jim McManus in 1921. He was working under that name in 1950, when he took a job hosting a sports show on WCBS in New York. A network executive wanted to call that show The Real McKay — so the host changed his name.The New York Times has this piece of information:
The next decade brought more television stints at WCBS-TV and the CBS network as a weatherman, a public-affairs moderator, a game show host and a sportscaster.
