From a September 3 TVNewser post:
Fox Business Network has announced, after weeks of speculation around the industry, that radio host Don Imus will be joining the network starting October 5th. Imus signed a multi-year deal with FBN to simulcast "Imus in the Morning" weekdays from 6-9amET along with his radio syndication. The announcement stated that Imus will be incorporating more business news into his format.
TVNewser had reported in early August that the host was in talks with FBN to bring the simulcast to the network. A few weeks later, Imus announced that he would be leaving RFD-TV much earlier than he had originally signed on for, furthering speculation.
Executive VP Kevin Magee made the announcement today saying, "We're excited to welcome a renowned broadcaster like Don Imus to the FOX Business team. His 40 years of on-air experience combined with his superb interviewing skills and capitalist sensibilities will be a great addition to our lineup."
