Nielsen Plays Catch-Up as Streaming Era Wreaks Havoc on TV Raters

Now, new rivals seeking to challenge Nielsen’s dominance have emerged. The latest came on Monday, when comScore, Inc. and Rentrak announced they were united after the closing of their merger. ComScore, founded in 1999, has expertise in measuring the use of digital media, while Rentrak uses data from set-top boxes to measure what people watch on television. Combined, the companies are seeking to measure audiences across screens — mobile, desktop, television and more. - Emily Steel, The New York Times [via/web:http://streaming-tv.us]
