New (1)newspapers (incl. shoppers, buy & sells, weekly and daily) and
(2) radio stations are starting up all the time. I would like to know
is it possible to find out who these "New" startups are...or who the
new listings are?
Question two: Is there one place in the Internet that offers the
"Best" site for finding information on these companies, where?

These are two rather different domains, and are unlikely to be found
in a single place.  In fact, finding information about newspapers all
the way down to weekly shoppers will be particularly difficult, since
there is probably no central licensing or registration institution

Radio stations, on the other hand, can probably be studied in some
detail at the FCC. The general site is:

  http://www.fcc.gov/

And all the public databases are at

  http://www.fcc.gov/mb/databases/cdbs/

And the general FCC search stie is

Good Luck.  --David.
