3. 1970It was during this first slump that Larry Stevenson invented the kick tail, and the first generation of skateboarders laid down the foundation of tricks and style. However, they were still largely limited by equipment. Then in 1973 the urethane wheel was invented, revolutionizing the sport. The new wheels provided much better traction and speed and, combined with new skateboard specific trucks, allowed skaters to push the difficulty of manoeuvres to new levels. Tricks at this time consisted of surfing manoeuvres done on flat ground or on banks. Empty swimming pools and cylindrical pipes were exploited as terrain for the first time. During the 1970's skateboarding experienced a large growth stage whish saw the construction of numerous concrete skate parks, a rank of professional skaters, magazines and movies. During this period modern skateboarding evolved to include vertical skating among its disciplines of slalom, downhill, freestyle and longjump.Key advances in the sport included the aerial, the invert and the Ollie, which may be the single most important trick in the evolution of skateboarding, next to the kick turn. This was the first time skateboarding had stars, some of the first really big names being Tony Alva, Jay Adams and Stacy Peralta. The look of skateboards also changed from being six to seven inches in width to over nine inches, providing better stability on vertical surfaces. Near the end of the 70's, spiralling insurance and slowing attendance forced all but a few skate parks out of business and skateboarding entered its! Second slump.
