"Along with flatland freestyle, slalom was one of skateboarding's original disciplines, taking obvious inspiration from slalom skiing. Virtually all major competitions in the 1960s and mid-70s featured a slalom event, including a famous show-down between Hester and Tony Alva televised on ABC Wide World of Sports as part of the 1976 Carlsbad Hang Ten World Championships.
Slalom was prime fodder for network sports television as late as 1978, when CBS Sports Spectacular broadcast the FreeFormer World Championships in Akron, Ohio. But momentum in the late 70s shifted decisively to aggressive styles, and by the early 80s the U.S. slalom scene had mostly dissipated."
