Who started the popular cheer called the wave?

Answer 1

There are many theories about where the wave started, here are a few

Bill the Beerman-Bill Scott, a Seattle bartender, started selling beer to football crowds at Seattle's Kingdome in 1976. He encouraged the crowd to follow his cheers.

Krazy Geogre-Some claim that the first appearance of the wave was a section by section cheer at a Major League Baseball game that was led by professional cheerleader Krazy George Henderson in Oakland, California on October 15, 1981, in an American League Championship Series game between the Oakland Athletics and the New York Yankees.

University of Washington-Many claim that the first wave originated in Seattle at the University of Washington's Husky Stadium on October 31, 1981,[3][4] at the prompting of Dave Hunter and Robb Weller. Weller, a Washington graduate, was the guest yell-king during the Huskies' homecoming football game against the Stanford University Cardinals.
