The History of DOTA 1

Defense of the Ancients was first released in 2003. It is a game consisting of three lanes where two teams of five players each are against each other. The name of the two teams are The Sentinel and The Scourge. The goal of the game is for one team to destroy the center base of the opposing team which is called the Ancient.

Dota 1 has since been developed by 7 persons. Its current developer is IceFrog and Valve. Different communities have expressed concern with the Dota franchise being under Valve. A legal opposition has been brought up and the dispute has ended on May 2012 favoring Valve's side. They gained the franchising rights  for commercial use to the trademark. Dota 2 was released on July 2013.
