Activision Blizzard posted a strong third quarter and its CEO said it is on track to have its most profitable year. The video game company took in $745 million in the quarter, up 6% from the same period last year. Through the first nine months of 2010, the company’s revenue is up nearly 10% to $2.02 billion.

During the earnings call, CEO Robert Kotick took the opportunity to highlight the company’s success in a time when many other entertainment options are struggling.

“In the landscape where many entertainment providers are trying to figure out how to manage lower audience engagement and rapid obsolescence, our core franchises are posting record engagement levels and seeing adoption curves that are longer, deeper and with sadder tails than ever before. And our players are enjoying a higher level of quality that we have ever delivered. Though we have performed so well during a period in which many consumer businesses beyond video games have seen only disruption and decline is not due to chance.”

Just how much time are gamers putting into these games? According to Nielsen, average weekly gameplay of Activision Blizzard’s StarCraft is over four hours per week and it has a monthly average of 180,000+ unique players since January 2008. In general, Americans spent 407 hours per month just on Internet games. That’s behind social media platforms (906 hours per month) but ahead of email (329 hours), instant messaging (160 hours) and video (156 hours).

Vivendi, the parent company of Universal Music Group, owns 52% of Activision Blizzard. Its roster of games includes music games “Guitar Hero” and “DJ Hero” as well as major franchises like “Call of Duty” and “World of Warcraft.”
