in the major American promotions; the last major hardcore title was the WWE Hardcore Championship, which merged into the Intercontinental Title in 2002. However, WWE still features a yearly pay per view event based around hardcore wrestling called WWE Extreme Rules. In 2006, the MTV-affiliated promotion/show Wrestling Society X featured hardcore wrestling, but was cancelled after one season. Rules The main rule behind hardcore can have various connotations. Thus, hardcore wrestling is often separated into distinct "levels" based on the graphic nature of the match: A 24/7 title match describes a situation where a hardcore wrestler must defend the title at all times and all places. The match (and the title) can be won by pinfall (or submission) at any time and in any place in the presence of a referee. The match has no fixed location, timeframe or even opponent (in certain cases even non-human animals or inanimate objects can become champions). This is one of the most severe forms of hardcore match given its unpredictability. This was initially a self-imposed stipulation of Crash Holly's WWE Hardcore Championship but afterward became a general rule of the title. During the time Holly defended his title, he did so in such locations as his hotel room, at the airport, in a supermarket, and even at an arcade. A no disqualification match, a no holds barred match, or an anything goes match tends to be less severe, with action taking place mostly inside the ring, despite most of the time there is a no countout stipulation. Usage of foreign objects is typically low and minimal, with run-ins (another form of disqualification) being frequently used. The match is often contested between valets (where they may lack wrestling skills), or between a wrestler and a valet (in which a wrestler is expected to run-in and defend their valets). Because of the low-key nature, few consider a no-disqualification match as hardcore, although there is no semantic difference. A street fight uses the various elements of "No Holds Barred" and "No Disqualification" and occasionally does allow pinfalls and submissions outside of the ring. The only real difference/variation is that in a street fight, wrestlers wear their street clothes instead of tights, although there have been street fights where the combatants wear their tights. Also, like an "I Quit" match, rope break does not apply, so having any part of the body against the ropes will not
