Hashmark

Hashmarks (also "hash marks") are marking lines (usually) on sports fields; they run orthogonally (perpendicular) to the sideline or its lateral boundary.
Use in American football
In American football , hashmarks are used to divide the playing field lengthways. In the NFL , they are drawn at a distance of 25 meters, for college and high school games at a distance of 18 meters from the sidelines.
If the ball is outside the hash marks after a play, the umpire places it on the hash mark for the next play. So there is always enough space for the offense to be able to make a move on both sides. If the ball comes to rest between the hashmarks after a move, the next move starts from this point.
In American football this marker lines were for the first time in NFL playoff game of the season in 1932 between the Portsmouth Spartans and the Chicago Bears used. Since both teams had six wins and one loss after the regular season (draws didn't count at the time), a playoff had to be played to determine the champions. The game was scheduled for December 18, 1932 . However, hours before it had snowed so much that the actual playing field could not be used. With an idea from George Halas , it was decided to play the game in Chicago Stadium , where the Chicago Black Hawks ice hockey team played their home games. Since it was an ice hockey field with solid boards on the side, there was a fear of serious injuries during the game, as the ball was snapped at the point where the last play had stopped or where the ball carrier went out of bounds. It was agreed that every move must begin at least ten yards from the sideline. Although this measure was initially intended to prevent injuries, it opened up new tactical possibilities for the game, so that the agreement was added to the game as a new rule in 1933 . The distance between the hash marks and the sidelines has increased over time. In 1935 and 1945, these were moved inwards by a further five yards. In 1972 , the last relocation of the hashmarks took place, to their current distance of almost 23 yards from the sidelines.
Use in ice hockey
Hashmarks at Hockey are marks at the bully -Kreisen (also called "Bully-point" or "Face-off point").
Two parallel lines (perpendicular to the sidebars) on both sides of the face-off circle represent the boundaries for the team's players. These must remain behind the imaginary extension of the hashmarks until the puck thrown in by the referee touches the ice and the game is restarted is.
