The week after his retirement was announced, Charlie Gibson was back on top of the evening news ratings. ABC's "World News" edged out "Nightly News" drawing 7.24 million Total Viewers to Nightly's 7.15M during the Labor Day week. That puts an end to Brian Williams' 46-week winning streak. "Nightly" still beat "World News" in the A25-54 by 20,000 viewers.

"World News" is based on a three-day average: Tuesday, Thursday and Friday. "Nightly News" is also based on a three-day average: Tuesday, Wednesday and Friday, while the "CBS Evening News" is based on a four-day average.

On the two nights the shows competed head-to-head, Tuesday and Friday, "Nightly" came in first in both Total Viewers the A25-54 demo, but still not enough to win the week.
