Look at the signal. Look at its limitations. I'd say that signal performed about as well as one could reasonably expect from a ratings standpoint during the past year or two. It earned stronger ratings than several Class B blowtorches in the market.
After a few months, I suspect there will be considerable ratings erosion, and I think over the next 12-24 months, billing will be flat or down from where it's been recently.
Most of the African American population in Greater Boston is concentrated within the city of Boston itself. To suggest African American listeners are too scattered or two few in number to make Urban AC viable on a limited Class A signal is a fallacy, in my opinion. The format was perfect for that signal, and it earned respectable ratings.
A 2019 version of Star 93.7 on a far crappier signal than 93.7 is going to post lousy ratings. I give the new station zero chance of lasting longer than two years. I predict the station will pivot back to Urban AC prior to the two year point.
The ding-a-lings in terrestrial radio keep repeating the same mistakes over...and over...and over. This type of format has not shown any longevity in just about every market it's been tried over the past 15 years.
