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. While these are good guidelines, I think they need to be taken as the recommendations they are, not any sort of steadfast rules.
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.
A regular hat trick in hockey occurs when a single player scores three goals in the course of an entire game, but other players may score goals in between that player's goals. In the NHL, a hat trick is usually rewarded with fans tossing their hats down onto the ice. It is said this tradition started in the 1950s.
