The Hartford Seminary's Hartford Institute for Religion Research, is one of the world’s leading and most respected religious research institutions. Its researchers keep a database on mega churches in the US. They define a mega church in part as having a weekly attendance of 2000 people.
Here is the link to the database:

I believe these numbers are from 2007. Can anyone verify the accuracy of these attendance numbers? I am somewhat familiar with the churches in California and the numbers seem to be very inflated.
