130 years of preaching has failed because most people aren't as stupid as the Governing Body thinks they are. The real Kingdom message is drawing in converts by the thousands every month and it doesn't require studying an apostate piece of crap literature in order to get baptised in the name of the Father, the Son and the Holy Spirit.
If the dubs came out of the fog they are surrounded in and looked around they would see the increase in Christianity. New churches everywhere and new additions to existing churches. Typical dub response when it is mentioned. "It's easy to throw money at a church but it is hard to give of your time." They just don't get it.
