I talked about this on an old thread a long time ago but I'll try to summarize. In KGO's heyday in the 80s/90s they were identical to an all news station 5 am to 9 am, and from 4 pm to 7 pm. Mornings after the news was a moderately liberal personality. At noon for about an hour there was a medical advice program. Then from 1 pm until 4pm there was a moderately conservative personality. The news of course from 4 to 7, and then another conservative personality fro 7 pm until 10pm. Then a more liberal personality from 10 pm until 1 am. Then a relatively "radical" personality from 1 to 5 am.
The station was perfectly balanced and intelligent , which is why many think that the old KGO was one of the nation's finest for its format.
