They just never developed a whole station that was better than the other stations. The morning show was given too much authority over its own operation, and did not follow PPM programming strategies. The music was not different or better and the talent on the other shifts was not superior to that on other regional Mexican stations.
There was also, throughout the GRC ownership, the feeling that "we are from Mexico City and we know how to do radio right" which may be true in CDMX but not in US Hispanic markets where they proved they did not know very much at all.
David, can you please give an example or two of what it is that they are not doing to maximize their "PPM programming strategies" that are common to other morning shows that are. How much are successful shows like Kevin and Bean attuned to maximizing "PPM Programing Strategies", and for those that have succeeded in both pre-and post-PPM worlds (such as Mark and Brian and Kevin and Bean), what types of changes did they do to alter their format when PPM came in? I find what I call "programming to the meter" to be one of the more interesting elements of station programming/management and that those who can do it successfully stand to be very successful and have done so.
