evrything that become very popular was and always will be the target of WTS-leaders.
When Tv started in the fifties, then internet in the nineties, all this was targeted...
however it developped in two was: in time more and more jW got used to new technology and used it despite warning of the Borg, on the other hand, to those happy in a cult, it does not make a real diffrence. If I want to be deceived, nothing, no TV, no internet no Facebook will awaken me...
So, I think, the growth will slow down due to information on the internet, but I do not think the demise will happen, my prediction:
The WTS will remain with a slow growth rate (mostly in developping countries), more financial cut backs, and ups and downs in tightening and loosing the bonds as they did the past decades...
