The 22,000-acre Tulalip (Tuh’-lay-lup) reservation is north of Microsoft's Redmond headquarters. The Tulalip Tribes operate a casino and resort, amphitheater, and outlets shopping center adjacent to Interstate 5. Apparently its name -- and perhaps its success? -- inspired the members of the Microsoft team who needed a code designation for their project.

The tribal council was not amused when Microsoft's project name leaked, and pointed out that the tribe's name is trademarked. Microsoft hastily contacted tribal officials, apparently convincing them that the term was intended for internal use only.
