In any market there are only a few network television stations to deal with. So while you have to search through tons of radio stations to find a handful you can use, you can do your thing on any network television station. That's because while each radio station keeps a specific audience all day long, each network television station will change its audience as it goes from program to program. Every day you can find cartoons, news, soaps, talk shows, sports, movies, late night programs, and more, all on one television station. You just have to be sure to select the correct programs on that station.
Cable television is purchased like radio first station by station.
Once you've chosen an appropriate station, you can go in and pick out particular programs on that channel to narrow down your desired target market even further. If you sell golf clubs, you might decide on ESPN as the cable channel . After that, you find the golf programs . You can also be more particular geographically when you buy cable, selecting only certain cities and suburbs rather than all the areas serviced by the station. Frequency is just as important when you use TV as it is when you use radio.
