On the eve of television’s upfront advertising market, Nielsen released a statement to clients urging them to use its legacy panels-only measurement system as currency, but said it will make its big-data plus panels measurement available for clients who want to use that to transact.
Nielsen had been planning to stop using its panel-based C3 and C7 currencies in September. Accreditation for that currency was restored this month by the Media Rating Council, which Nielsen noted made it the only company with an accredited system for measuring national TV audiences.
