A Note About August 2012 Video Metrix Reporting
With the release of August 2012 U.S. Video Metrix data, Comscore introduced three important methodological enhancements to our estimates that will affect data on a go-forward basis. The first enhancement is the incorporation of updated demographic universe estimates based on data from the 2010 U.S. census, which provides an improved accounting of the percentage of the population falling into each demographic segment. The second enhancement is an improvement in Comscore’s enumeration survey methodology to better represent persons in cell-phone only households. The third and final enhancement is a new technique to account for cookie rejection in Safari browsers, for sites measured via Comscore’s Unified Digital Measurement (UDM) methodology. Due to the effects of the changes to the August 2012 U.S. Video Metrix data, Comscore advises caution when interpreting month-over-month trends.
