I want to know the answer to the following question:
Which huge tech corporation moved its headquarters the Seattle area?
All the background I'm provided with is that "Beginning with Microsoft's 1979 move from Albuquerque, New Mexico to nearby Bellevue, Washington, Seattle and its suburbs became home to a number of technology companies including Amazon.com, RealNetworks, Nintendo of America, McCaw Cellular (now part of AT&T Mobility), VoiceStream (now T-Mobile), and biomedical corporations such as HeartStream (later purchased by Philips), Heart Technologies (later purchased by Boston Scientific),". Is that enough to answer the question?
