Thoroughbred Racing on CBS is the de facto title for a series of horse races events whose broadcasts are produced by CBS Sports, the sports division of the CBS television network in the United States. CBS first televised horse racing in 1948 with their broadcast of the Belmont Stakes. CBS would broadcast the Belmont Stakes the following year before losing the rights to NBC for the next three years. CBS would resume broadcasting the Belmont Stakes in 1953 and continue to televise it through 1985. A year after their inaugural telecast of the Belmont Stakes, CBS broadcast the Preakness Stakes, which they would continue to do so through 1976. In 1977, ABC was awarded the contract to televise the Preakness. Finally, CBS broadcast the Kentucky Derby from 1952-1974. The 1952 Kentucky Derby was the first to be broadcast on network television; Louisville had previously not been connected to network lines.
