The Los Angeles Sharks played just two seasons in the World Hockey Association (WHA) under that name, from 1972-1974. After the 1973–74 WHA season the franchise moved to Detroit to become the Michigan Stags, and again mid-season to Baltimore to become the Baltimore Blades.
The WHA lasted until 1979, by which time the Sharks were long gone. That meant that as far as pro hockey went in the city, the NHL’s Los Angeles Kings were once again the only game in town.
