One of the utterly marvellous things about pro wrestling is the fact that the performers are always manically inventing new things to do in the ring. In over a century, nobody has yet run out of interesting or exciting things to do inside the squared circle (and, just in case they ever do, TNA brought in six-sided rings in the 2000s). Because wrestling is an ever growing and expanding artform, wrestlers are always looking for ways to shake up their act and get noticed by fans and promoters. To this end, the 1990s and 2000s saw an influx of Mexican style Lucha Libre incorporated into US style wrestling, whilst the 1980s had wrestlers drawing influence from karate movies and the resultant explosion in popularity of the martial arts. The decade even enjoyed a small, but noticeable, trickle of British style shoot wrestling filtering into the American style. Wrestling is adaptable and highly absorbent. Within the tried and true gimmicks, characters, scenarios and stipulations on display at any given wrestling event, new moves are being born every day, inventive finishes are being tried out and wrestlers are looking to all manner of places for inspiration. Hardcore wrestling gave birth to a plethora of new matches, new spots, new moves and new scenarios, many of which are still being explored, recycled and restlessly improved upon, even today.
