After the demise of the Continental Indoor Soccer League, four of its teams decided to create a new indoor league to be called the Premier Soccer Alliance in 1998.

The World Indoor Soccer League (WISL) was formed through a merger between the US-based Premier Soccer Alliance and an English Indoor Football League, resulting in a name change from the original Premier Soccer League Alliance in 1999.

Initially, plans included a European Division with teams like London United and Manchester Magic, but this concept was scrapped due to conflicting rules and lack of approval from The Football Association.

In 2000, the World Indoor Soccer League (WISL) considered a groundbreaking move, attempting to become the first U.S. professional sports league to sell its naming rights.
