This allows for a slightly larger TV than the SMPTE recommendation, with a maximum screen size of 72 inches (again, 70-inch models are the closest) for a 9-foot viewing distance.

A hat trick in hockey is when a player scores three goals in a game. The term hat trick is often used in sports to refer to a player achieving three of something during a single competition, such as three goals in one soccer game, three hits in a baseball game or three touchdowns in an American football game.
In both codes of rugby football (rugby union and rugby league) a hat-trick is when a player scores three or more tries in a game. In rugby union, a related concept is that of a full house (scoring a try, conversion, penalty goal, and drop goal) in a single game.
