IAB sponsors the IAB Internet Advertising Revenue Report, which is conducted independently by the New Media Group of PwC. The results are considered the most accurate measurement of interactive advertising revenues because the data is compiled directly from information supplied by companies selling advertisements on the internet.

The survey includes data concerning online advertising revenues from web sites, commercial online services, free email providers, and all other companies selling online advertising. The full report is issued twice yearly for full and half-year data, and top-line quarterly estimates are issued for the first and third quarters. PwC does not audit the information and provides no opinion or other form of assurance with respect to the information.
