Remember Roger Mudd. He was a correspondent, but filled in as anchor when Walter Cronkite was absent. I don't remember him ever smiling. He was a fact machine that just seemed to report, with never a hint of bias or commentary. I thought for sure he would take over when Cronkite left for good, but they gave to job to a morning show host, Tom Brokaw, who was a wellspring of personality, probably a better image for the network, but lacked the business only personality of Mudd. I was disappointed. I thought Mudd was the better of the two, but that's just me. Mudd was hired for other positions on other networks, but none as prestigious as the evening news. He more or less fell off the map.
