Chicago Mayor Rahm Emanuel continues to rack up tourism successes for the city.
On Thursday, Emanuel announced that Microsoft would bring its "Ignite" conference would head to Chicago during the week of May 4-8, 2015.
Ignite plays as something of a meta conference for Microsoft, who will combine a series of smaller conferences -- TechEd, Microsoft Management Summit, The Exchange, SharePoint, Lync and Project -- into one.
The conference, which will take place at the McCormick Place Convention Center, is expected to draw upward of 20,000 tech entrepreneurs, engineers and investors.
It could be worth up to $47 million in revenue for the city.
