An interesting report has been published by Stephen Winzenburg, a communications professor at Grand View College in Des Moines, Iowa.  Winzenburg has followed television ministries for some years and has studied the amount of time actually comsumed by fundraising out of each program.  The results may surprise you.

A good deal of the report also contains his opinions about various television ministries.  I don't agree with some of his opinions, but the survey data is interesting.

Here's the report.
