I have to give a huge thanks to an anonymous collector for graciously providing me 3 of the Pocketpieces I was previously missing from 1979: 2nd June, 1st July, and 2nd July.
Below is a full Nielsen pocketpiece covering the 1st half of July 1979. It features the complete Nielsen ratings for all television programs airing in the weeks ending July 8, 1979 and July 15, 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.
