How not to write a radio spot
The first line of a radio spot doesn’t really say what you wrote. What it really says is “Keep listening because this will be interesting” or “Tune out because this will be boring.”
The latter variety is the more common.
I just heard another spot, written and produced by the station running it, that opened with “I’d like to tell you about [Blahblah]. It’s the [whatchamacallit] everyone is talking about.”
Everyone is talking about it? Then I’d say there’s no need to advertise it.
We all know the adage, If you can’t say something nice, don’t say anything at all. When it comes to ad writing, replace nice with compelling.
