same cost breakdowns, nor necessarily do vehicles within the print media. Following<br />

are the cost bases used:<br />

1. Cost per thousand (CPM). For years the magazine industry has provided cost<br />

breakdowns on the basis of cost per thousand people reached. The formula for this<br />

computation is<br />

CPM = Cost of ad space (absolute cost) × 1,000<br />

Circulation<br />

Figure 10-24 provides an example of this computation for two vehicles in the same<br />

medium—Time and Newsweek—and shows that (all other things being equal) Time is<br />

a more cost-effective buy, even though its absolute cost is higher. (We will come back<br />

to “all other things being equal” in a moment.)<br />

2. Cost per ratings point (CPRP). The broadcast media provide a different comparative<br />

cost figure, referred to as cost per ratings point or cost per point (CPP), based on<br />

the following formula:<br />

Cost of commercial time<br />

CPRP =<br />

Program rating<br />

An example of this calculation for a spot ad in a local TV market is shown in Figure<br />

10-25. It indicates that Survivor would be more cost-effective than CSI.<br />

3. Daily inch rate. For newspapers, cost effectiveness is based on the daily inch rate,<br />

which is the cost per column inch of the paper. Like magazines, newspapers now use<br />

the cost-per-thousand formula discussed earlier to determine relative costs. As shown<br />

in Figure 10-26, the Detroit News costs significantly more to advertise in than does<br />

the Chicago Tribune (again, all other things being equal).<br />

As you can see, it is difficult to make comparisons across various media. What is<br />

the broadcast equivalent of cost per thousand or the column inch rate? In an attempt to<br />

standardize relative costing procedures, the broadcast and newspaper media have<br />

begun to provide costs per thousand, using the following formulas:<br />

Television: Cost of 1 unit of time × 1,000 Cost of ad space × 1,000<br />
