In 1983, Knott's Berry Farm, in Southern California, was the first theme park to license the "Peanuts" characters, creating the first Camp Snoopy area and making Snoopy the park's mascot. Knott's expanded its operation in 1992 by building an indoor amusement park in the Mall of America, called "Knott's Camp Snoopy". The Knott's theme parks were acquired by the national amusement park chain Cedar Fair Entertainment Company in 1997, which continued to operate "Knott's Camp Snoopy" park until the mall took over its operation in March 2005. Cedar Fair had already licensed the "Peanuts" characters for use in 1992 as an atmosphere, so its acquisition of Knott's Berry Farm did not alter the use of those characters.
