27 February 2013 — Twenty American cities have been selected for the Bloomberg Philanthropies’ Mayors Challenge, the Huffington Post reports. The challenge is a competition designed to inspire America’s mayors to generate innovative ideas that solve major challenges and improve city life. “The 305 cities that applied come from 45 states and represent more than 64 million Americans. The submissions cover a diverse range of issues from a diverse range of cities,” the website reports. “This past fall, an all-star selection committee helped select 20 finalists. “City teams then came together at Bloomberg Ideas Camp, where they worked together with innovation, program, and implementation experts – to enhance and strengthen their ideas. The 20 finalists are now vying for a grand prize of $5 million and four additional prizes of $1 million.” See the full story, and the cities’ submissions, here.
