If you are in a geographic location where the television signal reaches the entire area that you serve, then tv is a possibility. Make sure your target audience watches the tv station you're considering running ads on. Again, the cost to reach 1,000 people is lower than through direct mail. However, many of the viewers you will be reaching live in apartments, may be out of your geographic area or don't have the cash to afford your products or services. Therefore your true cost per 1,000 people may be a lot higher.
Network tv advertising can be very expensive. The cost to advertise for 30 seconds on many popular tv shows is more than $300,000 - out of the reach of most contractors. However, the cost to advertise on the local evening news is within the budget of most contractors.
