Why is the 'Immortal Game', played in 1851 and still influencing books and films today, so named?

The "Immortal Game" was played by Adolf Anderssen and Lionel Kieseritzky in 1851. The game was significant and still influential because in the game Anderssen sacrificed both of his rooks to win the game. The game was later written up in the chess journal "La Régence." The strategy has been used to teach new players how sacrificing an important piece sometimes is the best move.

The Immortal Game was a chess game played in 1851 by Adolf Anderssen and Lionel Kieseritzky, with Kieseritzky losing. (The game seems by some reports to have been abandoned before its inevitable cnclusion, but is usually now published with the final moves included.)

Shortly after it was played, Kieseritzky published the game in La Régence, a French chess journal which he helped to edit. In 1855, Ernst Falkbeer published an analysis of the game, describing it for the first time with its namesake "immortal".

The designation is thought to have been made in reference to the bold and almost reckless style of play used. As this announcement of Samuel Tinsley's radio broadcast Talk on Chess in 1926 says,

"The Immortal Game" printed below is considered by many experts to be the greatest example on record of brilliant chess play. Chess is primarily a game of strategy. It is a fight, in which victory is not always to the big battalions. Play this game over. Note how Anderssen sacrifices piece after piece, each time strengthening his position, until his opponent is in a "mating net" from which there is no escape. This is the essence of chess. An accumulation of positional advantages.
