Ant writes “Colin Stewart’s OC Register Inside Innovation blog has up a post discussing Blizzard Entertainment’s success in the games industry. According to the site, Blizzard has learned eleven lessons on innovation that can help almost any business. The industry leader used these innovation methods not only to create the world’s most popular massively multiplayer online game, World of Warcraft, but also to keep the game fresh and challenging for more than 10 million players. Because many of those customers pay $15 a month to continue playing, Blizzard’s ongoing creative achievement is worth more than $1 billion a year in revenues, not counting the multi-millions it tallies from its other games.”.
