Two key trade groups representing opposite sides of the issue, the American Association of Advertising Agencies and the National Association of Broadcasters, Wednesday joined the groundswell of
industry voices calling on Nielsen to delay implementation of its local people meters until it can resolve issues and receive accreditation from the Media Rating Council. The AAAA voiced its concerns
in a letter to Nielsen CEO Susan Whiting, calling on her to resolve the system's sampling issues by July 31. The NAB board voted on a resolution urging Nielsen to hold off until the problems are
fixed.
