The Buss family — owners of the Los Angeles Lakers since the late Dr. Jerry Buss purchased the team in 1979 — has agreed to sell its majority stake in the franchise at a record $10 billion valuation, making this the most expensive sale of a U.S. professional sports team to date.

The Buss family’s decision to sell a controlling stake in the Los Angeles Lakers at a franchise valuation of $10 billion marks the end of nearly a half-century when one of the most valuable properties in the entire sports world was run by an eccentric father and his sometimes squabbling children.

The Lakers have been criticized over the years for pinching pennies, and one report revealed that they have cut costs to a concerning extent.
