Huge thank you to Bill for graciously providing me the last 3 of the Pocketpieces I was previously missing from 1979: 1st May, 2nd May, and 1st June.
Below is a full Nielsen pocketpiece covering the 1st half of May 1979. It features the complete Nielsen ratings for all television programs airing in the weeks ending May 6, 1979 and May 13, 1979. The first half of the report includes a full alphabetical list of all programs that aired and their two-week average HH rating/impression. The second half of the report provides HH ratings information for individual telecasts each day.
