I'm sure we have all thought at one time "Why hasn't the WT used televison to preach?" Or even to some extent now, the Internet.
Here in Britain we can get via satellite the various religious channels, God Channel, TBN, etc. We also have the Revelation channel founded by Howard Conder an exJW.
I was thinking can you imagine a Watchtower channel amongst those who are already broadcasting. What are they going to do? Have a brother give a 45 minute talk from a platform! A Watchtower study?? A drama ? Recordings of this years District Conventions?
The problem they would have is trying to make a program that would be entertaining that would hold peoples attention.
They would also be competing against all the other channels as well. People would be flipping between channels and wondering why the WT teach what they do and nobody else does. It would make people want to ask questions.
Even their own members would start to see differences.
Keeping the preaching work to one-to-one on the doors is a lot safer. 1) They are only dealing with one person at a time and can influence them. 2) Its also safer that their own members are kept a way from such channels as well.
The WT know that to go into the world of media etc would create more problems for them.
