The study determines and evaluates changes in the 10:00 p.m. newscasts of the Dallas-Fort Worth network affiliates following personnel and ownership changes, and a reduction in length of one station's newscast. Scripts and audio recordings of the newscasts were collected during four-week periods before and after the changes. The data were analyzed and supplemented with interviews conducted with the stations' news directors and producers. Conclusions drawn were that ownership changes had more impact on the presentation of the news than on its content, changes in anchormen and producers had more effect on presentation than on content, and a reduction in news time caused changes in the content of a television newscast.
