Phil:

I am not saying Rich's numbers are correct but I don't have a car but 
there are 10 working radios in my house and I have excluded those used 
for business or radio related reasons - like shortwave receivers. These 
are plain AM/FM or in 2 cases AM only radio. Clock and portable mostly. 
Lets look at this in the average home there is a radio probably in the 
kitchen and each bedroom. Then there is the den, living room and maybe a 
rec room. Patio radio, maybe the one built into the door bell/intercom 
and THEN there are the portables and boom boxes which would be at least 
one per child.  A family of four with a middle class sized house with 4 
bedrooms could easily have a dozen radios. That works out to three per 
person BEFORE you add in cars. Assume 3 cars and there are 3 more 
radios. Now add all the people in urban centers who do not own cars and 
the number easily comes to 3 or 4 times the population which is close 
top Rich's number. I bet there are close to 200 million sets in the New 
York metro alone.
