"World of Warcraft" (WoW), one of world's favourite online games, has reported big losses in its subscriber base. Over 600,000 players have left game in past three months. exodus has seen almost two million subscriptions ended in 2013. At start of year, Activision Blizzard, owners of game, boasted healthy 9.6 million subscribers. That figure is now 7.7 million. Despite huge decline, it is still easily world's most popular massively multiplayer online role-playing game (MMORPG). Analysts are saying drop is due to fierce competition from hugely popular multiplayer online battle arena (MOBA) games like "League of Legends," which has 12 million active daily players. Despite downturn in fortunes of WoW, Activision is pushing ahead to provide company with greater independence. Bobby Kotick, CEO of Activision Blizzard, is spearheading an $8.2billion buyout to be majority shareholder once again. He wants to buy 429 million of company's shares back from French telecoms and entertainment giant Vivendi. French company currently holds 61 per cent controlling stake in Activision, which would fall to just 12 per cent if acquisition is successful. Mr Kotick, who has been Activision CEO since 1991, is strong believer in future of online subscriptions. He oversaw success of WoW and another Activision smash hit, "Call Of Duty".
