MediaBuyerPlanner: Following the announcement from the consortium of private equity firms acquiring Dutch research conglomerate VNU that it had completed the purchase of 78.8 percent of VNU's shares, Susan Whiting, CEO of Nielsen Media Research, sent a letter to clients Monday, assuring that the consortium would stay committed to "continually investing in the growth and development of Nielsen Media Research," writes MediaPost.

"We expect the transition to new ownership will be seamless and transparent from your perspective," Whiting told clients, noting that Nielsen's priorities and commitment to its plan to measure television ratings as well as video content across all platforms would remain constant.

While Whiting didn't specifically tell how VNU's buyout would impact Nielsen's future plans, she did describe the acquisition as a "big advantage," saying it would create "an increased effort to bring together our marketing, media and entertainment assets on your behalf."
