Activision Blizzard has a very easy-to-understand business plan: monetize everything it can, as quickly as it can, across as many platforms as it can. The result is a strong slash-and-burn mentality when it comes to the games industry, and a new deal with Massive Inc. to sell ads in its games shouldn't come as a surprise; in-game advertising isn't a new idea. What's frightening is the announcement that those ads are coming to Battle.Net. Don't worry, it sounds like there are even more plans to turn Battle.net into a cash cow.
