Not all markets are equal. They have varying percentages in each of the age cells. They have various ethnic percentages. They have different work schedules and economic bases.
A market like McAllen - Brownsville - Harlingen is totally different from one like Eugene, OR.
So the success of different formats will vary. The availability of specific formats will vary. Even the radio advertising dollars will vary.
