For the record, Goodson did not axe Feud... low ratings did. A certain show with a spinning wheel hosted by a former weatherman knocked Feud out of the number 1 slot.
According to E! THS, Goodson did consider replacing Richard after the 1980 season. Richard was vacationing in Hawaii, and he threatened to stay in Hawaii unless he got a major raise, and control over whether to bring back families that lost unfairly. ABC, however, granted Richard what he wanted.
As for Holly and Bob, I wonder, if they find that Holly is telling the truth, and that perhaps Bob did sexually harass Dian, could that mean that Dian could sue Bob again?
