Tim Feran's radio columns were few and far between. He used to do one or two detailed, interesting pieces on the changes in Columbus radio per year, complete with quotes from lots of local industry people. But that stopped 7-10 years ago. As you point out, he does minimal media reporting now -- nor does anyone else at the Dispatch. At least at some point Feran finally stopped referring to CHR/Top 40 as "rock."
I've done a lot of archive research on Columbus radio in years past. The CJ had an active column with a local reporter from 1948 until their demise. The Dispatch has a much more spotty record. For example, I was reviewing 1955 looking for something. The Dispatch didn't have a regular column at that time. They carried mostly national wire service stories if they had any coverage of radio-tv at all. In the late 50's, they started a column written by Joe Mills. He continued until 64-65 and was promoted to the editorial page. Another gentleman took over and covered until 66 or 67. From then until around 1975 or 76, the Dispatch again had no daily coverage.
Two examples of stories not covered was Irwin Johnson's retirement in 1969 and when Bob Conners jumped ship from WTVN to WBNS in 1973. The Dispatch had zip coverage of those two events. Cynthia Robbins had started some periodic coveage bout the time Conners returned to tvn in 76.
