You can find information on bank failures at FDIC's page on Historical Statistics on Banking.
I pulled the information on the bank failure & assistance transactions from 1980 to 2009. Here is how it looks graphically:

Of course 2009 only covers through today so its a partial year.
As you can see the rate of bank failures in this decade is relatively small compared to the fallout from the S&L crisis in the 80's and 90's.
In most cases the failed bank was taken over by another bank. Only rarely does the FDIC have to completely take over the bank and liquidate. I'm not sure exactly what the difference between a "failure" and an "assistance" are so some of these might not be outright failures.
