I liken it to the gears of a car.
1st Gear: Up until the mid-2000s the internet was only available on the family PC or the worker with their laptop and internet access. Also WT was very scathing of the internet and gave it a red light.
2nd Gear: Mid-2000's onwards Smartphones and tablets became increasingly available and surfing the net in privacy became much more easy to all family members. WT gave an amber light to limited use of the internet by going on line itself.
3rd Gear: We've shifted into this gear with pre-teens and poorer countries getting smart technology. JWborg is in full flow with the internet being embraced with a tacit green light. JWTV is out there in all its awful parody/glory. Everyone from 9 to 90 is being encouraged to go on line to receive JW litter-ature. Trolley-Dolleys encourage the public to check out JWborg. (What else will they check?)
Result? Increasing concern, apathy, disbelief, quiet rebellion and out and out apostasy. In the field only the mentally ill come in and only the born-in kids get baptised.
