March Madness significantly impacts business productivity. Approximately 77.1 million workers spend at least an hour filling out brackets or discussing games each tournament. This costs businesses $1.2 billion in lost productivity per unproductive hour during the first week. While no one has ever picked a perfect bracket, Warren Buffett offered $1 billion to anyone who did in 2015. Bracket participation has grown substantially, with 70 million filled out in 2015 - 20 million more than the prior year.
