The nature of advertising will change. Broadcast
advertising will be superseded by a type of new media
marketing where individual promotional efforts can be
precisely measured in terms of success and increased
revenues. Traditional advertising is a very imprecise
activity. It is difficult to quantify the extra sales that
advertising stimulates. There are survey techniques to
estimate a campaign’s effectiveness but there is no way for
a company to measure the exact return on investment of any
the single promotional effort, or what exactly stimulated a
buyer to make a purchase.
