If I was an author of a book I think I would be over the moon if I was guaranteed a sale of around 5 million or more books for my work.
The Jehovah`s Witnesses have over 8 million members plus relatives that are fringe dwellers who come to the memorial once a year ,
So what a Gold mine they have been sitting on as a publishing house .
Why didn`t they keep publishing books for the faithful ,they could have even upped the price , and the faithful would have paid especially in prosperous country`s in the west.
They could have milked this venture for years to come as the faithful would have bought anything they would have published .
And their prophets (profits) would have soared ,literally and figuratively for many more years to come .
