Does Facebook advertising "work"?

Hello,

I gave a detailed response about real life advertising work
in Southern California. One, if not the biggest market in the world
for radio advertising.

I make a very successful living in California
promoting services to local audiences
using a variety of advertising tools...including
radio.

For over 27 years!

Now, my factual report about the local ad market
has been dismissed almost entirely, because I dared
to propose a different point of view!

Please, let's try to learn from each other instead
of running to defend our opinions.

Best,

Marshall

PS I will not respond to any other unsubstantiated opinion.
