The end of daylight-saving time and the midterm elections were ratings gifts for broadcast TV evening newscasts. Especially happy are the folks at NBC Nightly News With Brian Williams, which returned to the top spot in the news demo after ceding that seat for 11 weeks to ABC’s World News Tonight With David Muir. In that demo, Williams’ newscast clocked 2.19 million viewers to Muir’s 2.18 million; CBS Evening News With Scott Pelley drew 1.84 million demo viewers. NBC’s newscast also led among viewers of all ages: 9.45 million to ABC’s 8.76 million and CBS’ 7.25 mil.
