Games on ice: A look at labour disputes in the major pro team sports -- NHL, NFL, NBA and MLB

The National Hockey League lockout is the third labour dispute in less than two years in a professional team sports league. And it's the second one to force the cancellation of games.

A look at recent labour disputes in the four major professional leagues:

National Hockey League

Current lockout began Sept. 16, when training camps were to open. As of Wednesday, games have been called off through Nov. 1, a total of 135.

The previous lockout ran from Sept. 16, 2004 to July 13, 2005, and wiped out the entire 2004-05 regular season and post-season. The Stanley Cup was not given to a champion for the first time since 1919.

National Basketball Association

Last lockout ran from July 1 to Dec. 8, 2011 and wiped out training camps and nine weeks of the regular season. Teams' schedules were reduced from 82 to 66 games.

National Football League

Last lockout ran from March 11 to July 25, 2011, and wiped out the full free-agent signing period, training camps and the Hall of Fame game. The new agreement was put in place in time for a modified signing period, shortened camps and a full regular season.

Major League Baseball

Last lockout ran from Aug. 12, 1994 to April 2, 1995, and wiped out the remainder of the 1994 regular season and all of the post-season. The World Series was cancelled for the first time since 1904. All told, 948 games were lost.
