Biggest power play: In 2011, the social media company, then located in a San Francisco neighborhood known as SoMa, told the city it planned to relocate south, where so many other tech giants are. It would stay and continue to feed money into San Francisco offers, the company said, if it got a free pass on a payroll tax levied inside city limits.
City officials made a compromise: The 1.5% tax on employee salaries would be temporarily waived for any company that agreed to locate in the blighted Mid-Market neighborhood. Since then, tech firms including Zendesk, Uber, Pinterest, Dropbox, Airbnb, and Dorsey's other company, Square, have taken advantage of the so-called "Twitter tax break."
Dick Costolo was CEO of Twitter in 2011, while Jack Dorsey was executive chairman.
