Infomercials are a cash cow.
First of all you don’t have to buy programming. Now this isn’t as great as it seems as many shows are aired on a barter basis anyway, so the TV station doesn’t pay anyway.
But more importantly the TV station doesn’t pay staff. They don’t have to worry about will the programs bring in ratings, (whether they are bought or not). Then they don’t pay sales people to sell those programs they bought or bartered for.
Nielsen which tracks ratings also becomes less a factor. TV stations pay for Nielsen. Nielsen is NOT a scientific survey. (In their defense Nielsen never claims to be). The don’t rate total American viewers, their ratings are based on what advertisers want. This is why the ratings are often slammed as inaccurate, which they are, but again, Nielsen never claimed their ratings are accurate for total views, but merely what viewers the advertisers want.
Some (but not all) infomercials give a station a percentage of the call in following the shows that air.
The biggest thing is infomercials are so well reserached. The companies that produce them know, through a lot of consumer questions what should air when.
If an infomerical isn’t working the company can tell before the show is over and it then runs a new infomercial in its next spot. In a sense the infomerical company is programming.
So lets say “Acme Infomericals,” runs “RoadRunner High Speed” and the informerical does well. And it’s scheduled for 6 airings on WWWB-TV. The first four airings do well but the fifth dies. Well on the sixth Acme Infomericals pulls the infomercial for RoadRunner High Speed and replaces it with Coyote Ugly Beauty Products.
From a station viewpoint, there is no programming, no marketing, no sales people, no scheduling, there is nothing to do but provide the signal and if they make the cost of the electricity back (plus a few overnight salaries) it’s $$$$$$$$.
Now that digital is here it’s even more profitable as the station that doesn’t do high def programs can split its signal into SIX channels where before it had one.
