Speedway in Adelaide to see Australia's first demolition derby. Due to the size of the crowd (about twice the venue capacity), the police closed the speedway's gates. The derby itself had over 75 entries and lasted for over 100 minutes. Demolition derbies in Australia generally take place at speedways (usually on the opening or closing night of the season), with most cars being older model Australian-made sedans and wagons. ABC's Wide World of Sports televised the World Championship Demolition Derby from the mid-1960s until 1992. In 1972, the Los Angeles Coliseum hosted a demolition derby with mint-condition late model cars driven by Mario Andretti, A. J. Foyt, and Bobby Unser. The popular ABC sitcom Happy Days included the character Pinky Tuscadero, a female professional demolition derby driver and occasional love interest to the show's most popular character, Arthur Fonzarelli. Folk-pop singer Jim Croce wrote and sung about the sport in one of his popular songs, "Rapid Roy (The Stock Car Boy)" on his 1972 album, You Don't Mess Around with Jim. The sport's popularity peaked in the 1970s. By the 1980s, the sport's popularity began to wane. With the demise of Wide World of Sports, television exposure became scarce. In addition to safety concerns and the shortage of full-size vehicles, some felt that the sport has shown little change or innovation beyond its original premise. In 1997, The Nashville Network (later part of CBS) returned demolition derby to national television in its TNN's Motor Madness series of various motor-sport events. Motor Madness derbies were primarily for broadcast and needed to fit into a time frame. Live demolition derbies could last indefinitely. Motor Madness changed the rules from last car running to largest number of offensive hits in a time frame. However, as part of MTV Networks' takeover of CBS Cable operations in 2000, demolition derbies, as well as the rest of the CBS motor-sports operations, were removed from programming as part of MTV's move to shut down the CBS Charlotte operation based at Lowe's Motor Speedway and generalize the network into a more broadly viewed channel. Pay per view was demolition derby's only national television outlet in the 2000s (decade). Two $50,000-to-win derbies were held in Widewater, Canada, from 2000-2001. Later in the 2000s (decade), a proliferation of cable television shows about vehicle customizing occasionally showcased junked vehicles in bizarre competitions.
