South Park (Season 13) 720p - (2009 Lang: English)

The season was the first of three new seasons Parker and Stone agreed to produce for the network under a renewal deal. It consisted of fourteen 22-minute episodes, which aired in two groups of seven episodes separated by a six-month gap. Prior to the season's premiere, all South Park episodes were made available for free viewing on the official series website, South Park Studios. The 13th season was the first to be broadcast in high definition and in widescreen. Continuing their practice from previous seasons, Parker and Stone wrote and produced each episode within the week before its broadcast date.

The 13th season satirized such topics as the ACORN scandal, Japanese whaling, piracy in Somalia and the marketing tactics of the Walt Disney Company. Celebrities were spoofed throughout the season, including the Jonas Brothers, Kanye West, Carlos Mencia, Paul Watson and Glenn Beck, all of whom publicly responded to their portrayals. The episode "Fishsticks" attracted particular media attention due to rapper Kanye West's declaration that its jokes about his arrogance were funny but hurt his feelings. "The F Word", in which the central characters attempt to change the definition of the word "fag", was especially controversial and prompted complaints from the Gay & Lesbian Alliance Against Defamation. A broadcast of "Pinewood Derby" in Mexico was pulled, allegedly due to its depiction of Mexican President Felipe Calderón. "Fatbeard" was praised by the crew of the USS Bainbridge, which was involved in the 2009 rescue of the MV Maersk Alabama from Somali pirates.

The 13th season received mixed reviews: some critics called it one of South Park's strongest seasons, while others claimed the series was starting to decline in quality. The season maintained the average Nielsen rating viewership for the series, around 3 million viewers per episode. The episode "Margaritaville", which satirized the global recession then affecting much of the industrialized world, won the 2009 Emmy Award for Outstanding Animated Program (for Programming Less Than One Hour).
