Coming into the 1988–89 television season, networks had been struggling with a drop in ratings among children. ABC itself experienced a decline of 37 percent in kids under the age of 6. It had been surmised by ABC executives that this was due to a change in the way Nielsen ratings were collected. The data had historically been recorded automatically by a device inside household television sets. However this had been changed the year before; children now had to use people meters for their viewership to be counted. This required manually pushing buttons that would clock kids in and out and programs, something they often had trouble successfully completing. What resulted was a demographic that could not be guaranteed to advertisers.
