Money-making Niches!

Being highly attuned to such things, I always notice in TV programs there is always a fine old barometer hanging on the wall. I think its one of things that goes up automatically when the props department is told to dress a set.
When I had a retail store, a radio station convinced me to "sponsor" the weather for some horrific price, on the premise that "everyone is interested in the weather." While it is true, the interest does not seem to reach as far as their pockets. The best customers are those that use instruments to obtain information that will profit them.
