Challenge: Informally branded “March Madness,” the NCAA Division I Men’s and Women’s Basketball Championships are each single-elimination tournaments of 68 teams to determine the “Sweet 16,” the “Elite 8,” the “Final Four” and finally the “National Championship”. The men’s tournament has become one of the most famous and most watched U.S. sporting events of the year. Public interest, and thus media coverage, of March Madness is massive. Each year the NCAA faces the equally massive task of accepting and vetting thousands of time-critical credential requests from media across the country and beyond.
