the ecw brand initially tried to differentiate itself from wwe's other brands. the hard cameras were placed in a different location and the ring mat had an ecw logo on it. the male performers were also referred to as "extremists" as opposed to superstars, and female performers were called "vixens" instead of divas. it also had the first ecw talent. later however, changes were made to differentiate it from the original ecw promotion, including changing the original promotion's rules where weapons were legal in all matches and there were rarely any count outs or disqualifications. wwe now classifies such matches as having "extreme rules", and are only fought when specified. the only pay-per-view event hosted exclusively by the ecw brand since its launch was december to dismember in december 2006. on march 14, 2007, before another one could be scheduled, wwe announced that all future pay-per-views would feature all three brands.
