Last night the winning apps were rewarded at the NYC BigApps Awards Ceremony. It was an exciting event with Mayor Bloomberg and several leaders from City government in attendance. The "Investors Bar," where apps makers and entrepreneurs got to speak with some of the East Coast's finest investors, was packed all night.

Congratulations to the winning teams, which you can see here. PLEASE make sure to visit the gallery and write a congratulatory note to the winners.

Thank you to everyone who created an app, spread the word, added their support on the competition homepage, and played any part in the dissemination of City data or the running of the Challenge.
