The fourth season of the American animated television series SpongeBob SquarePants, created by former marine biologist and animator Stephen Hillenburg, was announced in November 2004. It premiered on May 6, 2005 with the episodes "Fear of a Krabby Patty" and "Shell of a Man," and ended on July 24, 2007 with the episode "Squid Wood."
Unlike the previous seasons' DVDs, season 4's was split into volumes. The volume one DVD was released in Region 1 on September 12, 2006, the volume two DVD was released in Region 1 on January 9, 2007, the season set was released its entirety in Region 2 on November 3, 2008, and on November 13, 2012, the entire collection of episodes from season 4 was released on DVD in Region 1.
Although series creator Stephen Hillenburg wanted the show to end after release of The SpongeBob SquarePants Movie to prevent it from "jumping the shark" and because SpongeBob SquarePants had peaked with the first movie, Nickelodeon wanted more episodes to be produced in accordance with high ratings and series-based merchandise sales. Thus, the show was renewed for a fourth season. However, Hillenburg resigned as the showrunner and appointed Paul Tibbitt.
In November 2004, Tom Kenny, Bill Fagerbakke, and the rest of the crew confirmed that they had completed four new episodes for broadcast on Nickelodeon in early 2005, and planned to finish about 20 total for the then-fourth season. In particular, Kenny said, "Kids were happy watching them for the 3,000th time. It was the parents who've been busting my chops for new episodes." He remarked that it would be "the same show, the same sponge."
