Speaking at an IAB event exploring online video and changing technology, Edwards highlighted how its gaming platform aimed to tap into changes in users' habits.
In an interview with Media Week, Edwards used Microsoft SmartGlass app as an example of a launch that benefits from Apple's iOS platform as well as Windows 8. It enables users view and control content across different devices such as PCs, tablets, and mobile phones.
He said: "It's going to be part of our open attitude to how content, and how Xbox, cross different devices".
The computer giant is focused on expanding its Xbox platform and working with brand partners to enhance the services it offers.
