This right here, I originally thought the Attitude Era was from the beginning of WrestleMania 14 to the end of WrestleMania 18 with the following of the Draft creating the piff Ruthless Aggression Era on Smackdown and the "GET THE F OUT!" campaign with WWE being the new name of the company.^Good posts up there, but for me, Attitude ended at the first brand extension. They was the first official reset button. Long time teams were split up, new ones were formed, and guys were getting gimmick changes. WM X7 may have been what lit the match for the eventual end, but it wasn't the end.
But with all the watch parties with by TSC family along with listening to tons of wrestling podcast it got me going back and reliving history looking at old classics with fresh eyes trying to piece together the timeline accurately.
