After having lost his job as co-host of CNN's American Morning last year, Miles O'Brien is being dropped by the cable news network altogether. O'Brien, who had earned much respect as the chief technology and environment correspondent for CNN, had spent 17 years with the cable network -- an "epoch" in the television news business, O'Brien said in a statement. CNN said "Miles has made many contributions to CNN over the years. He is a terrific reporter and we wish him all the best. Also losing their jobs will be six producers for CNN's science and technology unit, which is being shut down.
