NAB plans to establish an “academy” of radio execs to select Marconi Award winners. NAB’s EVP for Radio John David told board members about the plan this week at the winter board meeting. Group members would be anonymous and would include GMs, PDs, former radio execs, owners and consultants. NAB hopes to get the group in place before the fall radio show. The plan is designed to eliminate the perception of block voting by groups and campaigning by Marconi nominees.
