From the late 1960s through the early 1980s, several successful prime-time animated TV specials aired. Because these one-shot cartoons were aired during prime-time hours (and thus had to appeal to adults as well as children), they had to obtain higher ratings than their Saturday and weekday counterparts. CBS in particular allowed a large number of animated TV specials to air on its network, and several of these continue to be repeated annually and sold on video and DVD. The Rankin-Bass studio produced a number of stop-motion specials geared towards popular holidays (including "Rudolph the Red-Nosed Reindeer", "Frosty the Snowman", and "Santa Claus Is Comin' to Town"); while Bill Melendez's long-running series of "Peanuts" specials won numerous awards, spawned four feature films, and even launched a Saturday morning series. Other attempts to bring comic strip characters to TV did not have anywhere near as much success until one of the "Peanuts" directors, Phil Roman, brought the Jim Davis comic strip "Garfield" to TV starting in 1982, resulting in 11 specials and a long-running animated series.
