At the 2014 convention, Loesch got up there and was talking about playing videos for people at the door and said something about people asking if we were going back to old methods - like playing recorded sermons on a record player at the door - just with modernized technology. His retort was a blind assertion that this was totally different and just the standard reply of something like: "aren't we thankful for how quickly Jehovah's organization is moving and keeping pace with modern technology?" and of course an applause break follows and no one realizes that he completely failed to make a distinction between playing videos and the old days of playing sermons.
Another thing they've gone back to, but I'm not sure how much it's being used, is the modern day equivalent of the old testimony cards. Now they have the business cards with a QR code that'll take you to jw.borg.
I wonder when we'll be seeing waves of sound cars driving through the neighborhoods again?
