Born Irwin Elliot Shalek in Chelsea, Massachusetts and a graduate of the University of Michigan, Elliot did Rangers games through the 1950s and 60s, alternating with other announcers of the era, depending on what stations held rights and who sponsored the games.
Elliot broadcast boxing matches on the NBC radio network during the 1950s.
From 1947 to 1949, he was the emcee of Quick As a Flash, a radio quiz program which featured drama segments with guest actors from radio detective shows.
On TV, he replaced Jay Jackson as host of the nighttime version of the popular quiz show Tic-Tac-Dough, for the last 13 weeks of the show's nighttime run, before that program was taken off the air in the fallout from the quiz show scandals that had erupted not long before.
But Elliot became far better known as a sportscaster. In the mid 1960s, he was the announcer for the "Schaefer Circle of Sports" broadcasts of Rangers and Knicks games, track and field and other events related to Madison Square Garden. Those broadcasts aired on WPIX TV and later on WOR TV. He also called the 1966 Stanley Cup Finals (the first televised by an American network) for NBC.
Elliot also broadcast horse racing events in the 1960s and conducted one of the early call-insports radio talk shows on WCBS-AM in New York.
He then started anchoring Sports Central USA for CBS Radio, which he continued to do into the early 1980s. He also took part in several of the network's World Series broadcasts in the 1970s.
