For most of the period from 1975 to 2006, KNXT/KCBS-TV was not a major competitor in the Los Angeles television ratings among the area's local television newscasts. During the period, Channel 2 had frequently changed newscast titles (from "The Big News/Eleven O'Clock Report" to "Channel 2 News" in 1973, then to "Newsroom" in 1976 and back to "Channel 2 News" by 1978) and formats to styles that often became unsuccessful and even controversial. In September 1986, Channel 2 implemented a news-wheel format with each half-hour of news devoted to certain topics and themes (for example, there was entertainment and lifestyle news early on and harder news stories later in the program); this format was heavily panned by critics and audiences alike, and was dropped after only a month.
