I have to admit, Frosty's not my favorite (although he has a great sense of style) of the holiday lineup, but I feel compelled to include him in the holiday traditions.
"Frosty the Snowman" is a popular song (originally titled "Frosty the Snow Man") written by Walter "Jack" Rollins and Steve Nelson, and first recorded by Gene Autry and the Cass County Boys in 1950. It was written after the success of Autry's 1949 recording of "Rudolph the Red-Nosed Reindeer." Like "Rudolph," "Frosty" was later adapted to other media including the television special.
The American animated television special first aired on Dec. 7, 1969 and marked the first use of traditional cel animation (as opposed to stop-motion animation) for Rankin/Bass in a Christmas special. Rankin/Bass veteran writer Romeo Muller adapted and expanded the story for television as he had previously done with Rudolph the Red-Nosed Reindeer.
