When the professional opportunities mounted and began to intrude on baseball practice time, Coach Coombs talked with me and agreed that my voice would be a better weapon to get to the majors than my bat, and would certainly last longer. I was commissioned as a probationary ensign in the Navy Supply Corps and sent to Harvard Business School for a few months to learn accounting, which I found uninspiring although necessary. I was then sent, with the Seabees, to the Solomon Islands, where everything I'd been taught, which had been based on shipboard routines, proved inapplicable to life at an advanced base, where requisition papers were buried in the mud. In two weeks' time I was ordered back to Washington and assigned the task of rewriting the navy's advance base supply regulations and training manuals. I began broadcasting sports on the radio in Washington while I was still in uniform.
Radio is better suited for highlight calls.
The description dominates. On TV, it's the picture that counts, with the sportscaster adding the captions. Radio is describing everything that takes place. TV is complementing the picture with identification, analysis, and comments. TV leaves more time for creative effort, banter with a partner, and a more conversational approach.
