user: Please give me a summary of the text on the origins of skateboarding.

The first skateboards started with wooden boxes, or boards, with roller skate wheels attached to the bottom. Crate scooters preceded skateboards, having a wooden crate attached to the nose (front of the board), which formed rudimentary handlebars.[7][8][9] The boxes turned into planks, similar to the skateboard decks of today.[1]

Skateboarding, as it exists today, was probably born sometime in the late 1940s, or early 1950s,[10] when surfers in California wanted something to do when the waves were flat. This was called "sidewalk surfing" – a new wave of surfing on the sidewalk as the sport of surfing became highly popular. No one knows who made the first board; it seems that several people came up with similar ideas at around the same time. The first manufactured skateboards were ordered by a Los Angeles, California surf shop, meant to be used by surfers in their downtime. The shop owner, Bill Richard, made a deal with the Chicago Roller Skate Company[11] to produce sets of skate wheels, which they attached to square wooden boards. Accordingly, skateboarding was originally denoted "sidewalk surfing" and early skaters emulated surfing style and maneuvers, and performed barefoot.[7][1][12]

By the 1960s a small number of surfing manufacturers in Southern California such as Jack's, Kips', Hobie, Bing's and Makaha started building skateboards that resembled small surfboards, and assembled teams to promote their products. One of the earliest Skateboard exhibitions was sponsored by Makaha's founder, Larry Stevenson, in 1963 and held at the Pier Avenue Junior High School in Hermosa Beach, California.[13][14][15] Some of these same teams of skateboarders 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.[16]

As the popularity of skateboarding began expanding, the first skateboarding magazine, The Quarterly Skateboarder was published in 1964.[1] John Severson, who published the magazine, wrote in his first editorial:

Today's skateboarders are founders in this sport—they're pioneers—they are the first. There is no history in Skateboarding—its being made now—by you. The sport is being molded and we believe that doing the right thing now will lead to a bright future for the sport. Already, there are storm clouds on the horizon with opponents of the sport talking about ban and restriction.[17]

The magazine only lasted four issues, but resumed publication as Skateboarder in 1975.[17][18][19] 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.[20][21] Because skateboarding was a new sport during this time, there were only two original disciplines during competitions: flatland freestyle and slalom downhill racing.[7]

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.[22][23]

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. McGee made the cover of Life magazine[1][24] in 1965 and was featured on several popular television programs—The Mike Douglas Show, What's My Line? and The Tonight Show Starring Johnny Carson—which helped make skateboarding even more popular at the time.[25][26][27] Some other well known surfer-style skateboarders of the time were Danny Bearer, Torger Johnson, Bruce Logan, Bill and Mark Richards, Woody Woodward, and Jim Fitzpatrick.

The growth of the sport during this period can also be seen in sales figures for Makaha, which quoted $4 million worth of board sales between 1963 and 1965.[28] 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[28] and Skateboarder Magazine had stopped publication. The popularity of skateboarding dropped and remained low until the early 1970s.[8][29][30]

assistant: Sidewalk surfing, known today as skateboarding, originated in the late 1940s out of the desire of California surfers hoping to still ride when waves were flat. By the 1960s, a small number of surfing manufacturers began selling skateboards hoping to bring more attention to the sport. Skateboarding began to rapidly increase in popularity in the 1970s due to improvements to the design elements and materials used on the boards.
