Munch Madness has begun.

The third annual promotion of the U.S. Apple Association pits apple varieties against each other in popular votes tournament-style.

Organizers ask apple eaters to visit to vote for their favorite varieties through the different stages of the tournament. The contest includes the top 16 selling varieties.

The pun-heavy promotion runs through the end of March. There are even Facebook and Twitter accounts.

The U.S. Apple Association is a Virginia-based trade group representing all segments of the apple industry in the United States.
