The National Lacrosse League is the North American professional league of men's indoor lacrosse. The rules of indoor lacrosse and the box lacrosse, the ancestor of indoor lacrosse, differ but these differences have diminished over the years; the key discrepancy in rules now is that in indoor lacrosse still only hollow sticks are allowed. Contrasting other lacrosse leagues, played in the summer, the National Lacrosse League holds its matches in the winter. Every year, the playoff teams compete for the Champion's Cup.
The National Lacrosse League was created in 1997 on the foundation of the Major Indoor Lacrosse League, with the resolution to switch from league ownership of all lacrosse teams to individual ownership of the teams. The Major Indoor Lacrosse League was founded in 1986 and originally was called the Eagle Pro Box Lacrosse League. The debut season of the Eagle Pro Box Lacrosse League was held in January 1987. In 1988, the name of the league was changed to Major Indoor Lacrosse League. The MILL dispersed in 1997 at the time when the NLL was founded with five MILL teams joined the National Lacrosse League. It's worthy of note that the National Lacrosse League identifies the history of Major Indoor Lacrosse League as its own.
In February 2005 the National Lacrosse League made known, that Activision would develop a NLL computer game. The game will most likely be introduced for the 2006 NLL season.
In May, 2005, the National Lacrosse League announced that the inactive franchise of Ottawa Rebel had been acquired and shifted to
