Nice information. By the looks of it (not including the MI teams, I will wait for the final 3) there have been:
14 - 1st time winners
10 - 2 time winners
3 - 3 time winners
4 - 4 time winners
2 - 5 time winners
1 - 6 time winner

Some of the more impressive data is the teams that haven't won the award in a number of years returning to win it again.
342 has the longest gap since last winning (2005)
122, founded in 1997, won it's first CA this year

As for when teams started 2005 has the most (currently)
2005 has 8 winners (both the Championship RAS and RI are represented)
2000 has 6 winners


The most consecutive years winning a CA goes to 234 (4 straight years - very impressive)

1511 is (so far) the only team to win both a CA and EI this year.

There's lots more fun stuff if you want to know
Number of teams that have won at three or more different regionals - 5
Number of (3 or more CA's) that have won at only 1 regional - 2
There are 3 consecutive numbered teams that have won CA's 340, 341, & 342.

1 more week to go.

Congrats to all winners. It is hard work to win a CA, you should be proud of your accomplishments.
