Valve usually supports the Major event in collaberation with different organisers. The latest tournament, ESL One Cologne 2016, ended about a month ago, with the brazillian team FalleN as winners.
Now it is already announced that the next Major will be held in January, but no organiser has yet been revealed. A few players have criticised this decision since most of them are off on holiday during Christmas, and need a little time to get back in the game.
