In the hockey world, it's simply known as "The Trade."
On August 9, 1988, the LA Kings acquired Wayne Gretzky, Marty McSorley and Mike Krushelnyski in exchange for Jimmy Carson, Martin Gelinas, first round draft picks in 1989, 1991 and 1993, and $15 million in the most substantial trade in NHL history.

The trade occurred less than three months after Gretzky led the Oilers to their fourth Stanley Cup championship in five seasons, winning the Conn Smythe Trophy as postseason MVP for the second time.
In an interview with LA Kings Insider, LA Kings President Luc Robitaille said he was in Montreal at the time of the trade and had heard, like many closely connected to the sport, that there was definitely substance behind the smoke. He said he recalled hearing "some rumblings" in advance of the trade before then Kings owner Bruce McNall called him two or three days prior to express confidence that it would ultimately happen.
"I think down deep, I still didn't believe it," Robitaille said. "I didn't believe that the best player in the world, at his peak, would be traded. Later, he did tell me - I don't know if it's true - but they had asked for me, and [Bruce] had told me he would never trade me. That's the reason it took a few more days."
Gretzky turned the Kings into an attraction in star-driven Los Angeles, drawing sellout crowds and launching a new era of hockey.

At the time of the trade, the then 27-year-old Gretzky was already the most dominant player of his generation, holding single-season NHL records for goals (92), assists (163) and points (215).
He was the League's all-time assists leader with 1,086 and sat 218 goals and 181 points behind Gordie Howe for No. 1 all-time in those categories.
