Nielsen has mixup over sweeps postcards

Published on .

Nielsen Media Research had a big snafu during the recent November sweeps. In week three Nielsen sent out 40,000 postcards reminding viewers to send in their diaries; the postcards arrived either before or just after the diaries. Then, in week four, 40,000 postcards were supposed to go out telling viewers to expect the diaries but were never sent.
