With a bit of lockdown boredom and following this comment
a bit analysis of the brekky trend for 3MMM:
For the purpose of the analysis, I have split the Hot Breakfast into eras (or should that be eons?) based on the hosts. Not unsurprisingly, the Ed, Luke & Mick era was the most successful, although the drop at the end of 2016 surprised me.
In terms of the reduction in brekky ratings with Marty Sheargold, it is pretty similar to the overall station performance, so not sure whether this a chicken or egg situation.
Each brekky analysis is fairly consistent in that a new host(s) typically results in a drop in brekky ratings then a rebuild, so at this stage I agree with @Qwerty that the performance of the Marty Sheargold show itself it isn’t terminal.
However, the problem is that the overall station performance is starting to feel a bit deja vu 2009 when Pete & Myf were hosting brekky and the overall station rating fell below 5.0% (surveys 7 and 8 of 2009 were the nidar at 3.9%). I suspect that there is an element of panic for any commercial FM station that falls below 5.0%. So probably not good times at 3MMM…
