There was big news recently in the local TV measurement space in the ongoing battle between Nielsen and comScore.
First, E.W. Scripps is adopting comScore across their 33 stations.
Second, Hearst is re-upping with Nielsen across their 30 stations.
Finally, CBS is thinking about dropping Nielsen on both the national and local front (14 stations). This appears to be more of a negotiating ploy but would be impactful none the less.
