"The Spirit of Christmas" introduced both South Park's distinctively primitive animation style -- its figures and backgrounds all created on construction paper cut-outs -- as well as the show's primary characters, foul-mouthed third-graders Stan, Kyle, Cartman and Kenny. Stone and Parker ultimately signed with the cable network Comedy Central to produce a weekly South Park series which debuted on August 13, 1997 with the episode "Cartman Gets an Anal Probe; " seemingly overnight the program became a national phenomenon, its characters even appearing on the cover of Newsweek magazine. The series' raunchy language and off-color plotlines also became the target of considerable controversy, which of course only made it more popular, particularly among the younger set.
By early 1998, South Park was everywhere -- the highest-rated program in Comedy Central history, it was also one of the highest-rated series on cable, drawing unprecedented viewership. A deluge of merchandising soon flooded the market, including T-shirts and home videos; rumors also circulated about a feature film. South Park's connection to the pop music scene was a major element of the series from its inception -- Primus' Les Claypool performed the theme song, Isaac Hayes voiced the recurring character Chef, and guest stars included the Cure's Robert Smith -- and so it came as little surprise when Chef Aid: The South Park Album was released in late 1998. The record featured contributions from Elton John, Master P and Ween, among others. ~ Jason Ankeny, All Music Guide
