Hallmark Hall of Fame is an anthology program on American television, sponsored by Hallmark Cards, a Kansas City-based greeting card company. The longest-running primetime series in the history of television, it has a historically long run, beginning during 1951 and continuing into 2015. From 1954 onward, all of its productions have been shown in color, although color television video productions were extremely rare in 1954. Many television movies have been shown on the program since its debut, though the program began with live telecasts of dramas and then changed to videotaped productions before finally changing to filmed ones.
