#2 nWo
The New World Order was so big that it nearly drove the WWE out of business. Debuting in WCW and consisting of legends such as Scott Hall, Kevin Nash, and Hulk Hogan, it was the single most important stable of The Monday Night Wars.
The only reason that the WWE survived was the rise of Stone Cold Steve Austin and the Attitude Era while on the WCW side of the things, nWo became too big for its own good and eventually crumbled under its own weight.
