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.
Hat trick was first recorded in print in the 1870s, but has since been widened to apply to any sport in which the person competing carries off some feat three times in quick succession, such as scoring three goals in one game of soccer.
