The earliest filming of the World Series was a special produced by Binion's Horseshoe in 1973 and narrated by Jimmy "The Greek" Snyder. CBS began covering the World Series in the late 1970s. In the early 1980s, the event was again broadcast as specials. In the late 1980s, the World Series returned to television as ESPN took over broadcasting. Initially, coverage consisted of just a single one hour taped delay broadcast of the main event.
