The Nielsen Co., known for its ratings service, is asking its customers to participate in a new "client satisfaction" study in order to rate itself, MediaDailyNews reported Friday.

Dave Thomas, Nielsen's president of media client services, sent a a notice to clients Thursday asking them to participate, calling the study "vital to ensuring Nielsen continuously meets your needs and expectations." The online survey will be done through the company's online research division, with e-mail invitations being sent to clients beginning Friday.

Nielsen has recently announced it will cancel its yearly meeting with clients next year, due to economic difficulties its customers are experiencing.

The study also comes as television networks have complained the group's core methods are incapable of measuring the current TV environment, as well as customers being upset over "a series of data processing glitches" that led to Nielsen reprocessing and reissuing several ratings reports, MediaDailyNews reported.
