Television is an effective medium for getting a message to a huge number of people, but, as a recruiting tool, network advertising has significant drawbacks:
With the advent of cable TV, some public access channels now offer television classifieds. These tend to be more reasonably priced than a traditional 1 1/2 minute commercial. Some job services, such as temporary agencies and state job services, are also using television as a medium. If you tend to stray from public access channels, though, in favor of a network channel, you could be looking at sky-high costs.
Radio, on the other hand, has some advantages:
Like television, radio's usefulness tends to be limited to those times when
an employer needs to hire a large number of people in a short span of time. One
nice thing about radio advertising is that many people listen in their cars,
which makes them, to some degree, a captive audience. However, among tried and
true recruiting methods, radio is not a top choice.
