”I joined the DirectX team in February ’99 to work on graphics APIs,” Seamus said in a later interview.

In 2001, Blackley helped create and design the Original Xbox.

”The purpose of creating any console, including the Xbox…my thought while writing the memo for the thing that became the Xbox and risking my career to show it to Bill was that we could make a device that was purpose-built to play awesome games,” Seamus said in a 2012 interview with Digital Trends.

Blackley added: ”It was a really hard decision to leave because working on the Xbox team was like being a Green Beret.” His resignation from Microsoft comes after a series of Microsoft Xbox price-cut announcements and just before the start of the games industry trade show Electronic Entertainment Expo.

After he left Microsoft, Seamus founded Capital Entertainment Group with former Microsoft co-worker Kevin Bachus.

In 2007, he received the P.T. Barnum Award from Tufts University for his work in the field of media and entertainment.
