Scott Hillis at Reuters reports that Microsoft’s Massive video game ad unit has signed a deal with Electronic Arts for ads in their vastly popular sports games. The deal includes the PC and Xbox 360 versions of “Madden” football, “NASCAR,” “Tiger Woods” golf, “NHL” hockey and the upcoming “Skate” skateboarding games. Financial terms were not revealed. While it wasn’t explicitly described as such, this looks like at least a partial continuation of a similar agreement EA signed with Massive last year.
