were also featured on a television show called Surf's Up in 1964, hosted by Stan Richards, that helped promote skateboarding as something new and fun to do. As the popularity of skateboarding began expanding, the first skateboarding magazine, The Quarterly Skateboarder was published in 1964. John Severson, who published the magazine, wrote in his first editorial: The magazine only lasted four issues, but resumed publication as Skateboarder in 1975. The first broadcast of an actual skateboarding competition was the 1965 National Skateboarding Championships, which were held in Anaheim, California and aired on ABC's Wide World of Sports. Because skateboarding was a new sport during this time, there were only two original disciplines during competitions: flatland freestyle and slalom downhill racing. Animated cartoons of the time occasionally featured skateboard gags. Two Road Runner cartoons made in 1965, Shot and Bothered and Out and Out Rout, feature Wile E. Coyote riding a skateboard. One of the earliest sponsored skateboarders, Patti McGee, was paid by Hobie and Vita Pak to travel around the country to do skateboarding exhibitions and to demonstrate skateboarding safety tips.

By 1966 a variety of sources began to claim that skateboarding was dangerous, resulting in shops being reluctant to sell them, and parents being reluctant to buy them. In 1966 sales had dropped significantly and Skateboarder Magazine had stopped publication. The popularity of skateboarding dropped and remained low until the early 1970s. 1970s In the early 1970s, Frank Nasworthy started to develop a skateboard wheel made of polyurethane, calling his company Cadillac Wheels. Prior to this new material, skateboards wheels were metal or "clay" wheels. The improvement in traction and performance was so immense that from the wheel's release in 1972 the popularity of skateboarding started to rise rapidly again, causing companies to invest more in product development. Nasworthy commissioned artist Jim Evans to do a
