There's an overhead screen in Beijing that measures 250 meters long and 30 meters wide. On November 21st, one man rented it to play a massively multiplayer online game (MMO). He probably paid about $15,000 to do so:
It is Asia's largest and the world's second largest LED screen at present. According to understanding, as the guild leader of a famous online game, the mentioned man spent a large sum of money playing the game via this giant sky screen for the sake of distinguishing gaming experiences.
