When I was a pioneer in the early 1960's I would go door to door Sunday mornings and all you could hear house to house were the Sunday morning T.V. preachers. I knew then that numbers don't lie if you want to get your message out you needed a complete assault.......... publications, boots on the ground,radio....T.V.
They cut their throats by ignoring the greatest communication opportunity available and open to everyone who could pay for TV time.
Why didn't they take advantage of having their own T.V. studio and broadcasting to the 8 million New Yorkers at the very least? Of course I am glad they didn't.
And how long did it take them to catch up to the internet?
My answer is simple they were and remain a 19th century religion 130 years later and they still can not communicate to the public at large.
In my opinion they were a reasonably successful real estate holding company but as a religion a bust.
P.S. I checked our local once a week newspaper which provides a free page for all religious Church's, centers, or meeting places to list their meetings and/or services. They are all listed even the Buddhists. I live in a tourist area but if you didn't have personal knowledge of where the KH was or what day and time they meet you would have a heck of a time attending.That of course is a good thing.
