I think the early days of the Watchtower Society were pretty high tech.
Russell had 20 million readers of his newspaper column. The Photo Drama of creation was pretty cutting edge for its time.
Rutherford's victrola recordings "Religion is a snare and a racket" must surely have capture people's attention.
He had a radio show where he lambasted other preachers pretty vociferously.
The Frank and Earnest radio program was popular.
But, TV never appealed to the Watchtower Society at all. Think about that.
Just about any weirdo with a pompadour can make millions with a TV ministry and the JW's avoid it like the plague.
Interesting, huh?
