Don Imus's frequent appearance in cowboy hat, flannel shirts and boots may have been just what it took to get him back on television. Published reports indicated today (Tuesday) that Imus's new radio show, which goes on the air on New York's WABC-AM on Dec. 3 (and is due to be syndicated by ABC Radio), will be simulcast by RFD-TV, a Nashville cable network that focuses on rural areas. Patrick Gottsch, RFD-TV founder and president, would only confirm that he was in talks with Imus, but he told the Nashville Tennessean Monday, "The biggest obstacle we've had in the last three years is convincing urban-based program directors in New York, Washington, D.C., and Los Angeles, and so on that they need to be carrying this 'rural' network. Imus helps us cross those borders."
