to 21. Cricket During the 2009 season of the Indian Premier League of T20 cricket, the halfway point of each innings contained a seven-and-a-half minute television timeout, two-thirds of which were devoted to additional advertising time. After complaints by viewers and players (criticizing its commercial purpose and for breaking the flow of the game), the following season replaced them with two sponsored and compulsory two-and-a-half minute "strategic timeouts" that must be taken by each side at certain points during the innings; one must be taken by the bowling team between the 6th to 10th overs, and the batting team between the 11th to 16th overs. Floorball In floorball, each team is allowed one thirty-second time-out per game, which may only be taken during a normal stoppage of play. The time-out is measured from when all the players are gathered around the team benches. Gridiron football In gridiron football, the use and rationing of time-outs is a major part of clock management strategy; calling time-out stops the clock (which normally is running between plays except in the case of a penalty, an incomplete pass, officials requiring time to re-spot the ball and/or down markers, or when the ball is run out of bounds), extending the time a team has to score. Timeouts can be called by both players (typically the quarterback or a linebacker) and the head coach. The number of timeouts is limited to three per team per half in the National Football League, and college and high school levels; to two per half in amateur Canadian football, and to one per half in the Canadian Football League. Unused timeouts carry over between the first and second quarters and between the third and fourth quarters, but they do not carry over between halves. If overtime is required in the NFL, each team is given two timeouts during a ten-minute regular season sudden-death period (overtime periods are fifteen minutes in the playoffs), while in college football each team gets one timeout per possession. In the CFL, overtime is untimed and teams receive no additional timeouts. If a timeout above these limits is called, it is usually ignored and no penalty is assessed (however, in many leagues, a coach attempting to call a timeout when he has no timeouts left can be assessed a 5-yard Delay of Game penalty). Teams use several methods to stop the clock without exhausting a timeout. These
