In Deciding Which Trade Shows to Attend, Some Business Marketing

In deciding which trade shows to attend, some business marketing strategists turn to reports published by Exhibit Surveys, Inc., a company that surveys trade show audiences. One useful measure that they provide isolates the percentage of the show audience that has decision authority for the types of products being exhibited. This is called:

A) Surveys of Industrial Purchasing Power.
B) Controlled Audience Index.
C) Total Buying Plans.
D) Buying Power Index.
E) Net Buying Influences.
