You have to consider that the average household is 3-5 people. So maybe the best case is an exposure of close to a billion.
But which billion? Its Europe (Eastern & Western) North and South America, Sub-Saharan Africa and the Rich Rim of the Pacific Asian countries.
That's where JW's are already. The Moslem countries, India and China must be doomed.
JW's are the beneficiaries of the mass conversions (often violent conversions) of the Dark Ages.
