From the article:

… Google supported NTS [NORAD Tracks Santa] from 2007-2011 and helped increase NTS program awareness across the globe; NORAD is grateful for the partnership and the resulting success. This year, NTS and Google mutually agreed to go in new directions, and we are excited to welcome a number of new contributors, to include Microsoft, Windows Azure, Bing, and iLink-systems, among others, to help us in our mission of tracking Santa. The ability to work with a diverse team of contributors is fundamental to the NTS mission, and we appreciate all of the continued support of all contributors.
