Here, we will try to understand how media influences us negatively.
They will only make the negative influence of media more obvious.
Let's extend this example by continuing this hypothetical campaign. On the Thursday after the Super Bowl, the advertiser does one more media blitz ?showing an encore of their Super Bowl ad on all major networks during the prime time slot of 8:00 to 8:30 PM. This practice of advertising on multiple channels at the same time ensures that most people will see the ad regardless of which channel they watch. Table 2 shows the viewer data, collected from households across the country, with the percentage of households who were watching during various combinations of the three time slots.

GRPs of this media plan were 144 and reach was 70, because 30% of households did not watch during any of the three times the ad was shown, resulting in an average frequency of 2.1. The frequency distribution of the plan is in Table 9B. That is, 23 percent of the households watched the time slot three times, 28 percent twice, 19 percent once, and 30 percent did not watch at all.

Thus, reach indicates the media dispersion while frequency shows the media repetition. Notice that the formula for frequency can be flipped to make a formula for GRPs; GRPs are the product of reach multiplied by frequency. If a media plan calls for a broad reach and a high frequency, then it calls for very high GRPs (lots of ad exposures to lots of people). Achieving a very high GRP is very expensive, however, and budget issues may preclude such a high GRP. Thus, media planners may start with budget, then estimate the GRPs that they can afford and then either sacrifice reach to maintain frequency or let frequency drop to one in order to maximize reach.

Media planners often think in terms of gross rating points because ad prices often scale with this measure. As a rule of thumb, it costs about twice as much to obtain a GRP of 84 as to obtain a GRP of 42. A media plan that calls for a GRP of 84 doesn't necessarily mean that the advertiser must advertise twice on the Super Bowl. The advertiser could also buy 6 spots on popular primetime shows that each have a rating of 14 (6*14 = 84) or buy a large number of spots (say 42 spots) on a range of niche-market cable TV programs, radio stations or magazines that have a rating of 2. Some media vehicles are best-suited to specific target audiences. For example, the Nickelodeon TV channel controls 53% of kids GRPs.[
