@Nicolaou, I don't think the older ones are watching it. Many don't even own tablets. In my elders' attempt to help strengthen my faith, they had me study with an older pioneer. I asked her what she made of the generation chart the GB came up with on the broadcast and she had no idea what I was talking about. She doesn't watch them and I honestly don't even think she knew about the changed teaching. Not too surprising since she is a 1975 denier even though she was around and in the Org during that time.
Some KHs do stream the broadcast if they have the capability.
I'm really glad for the broadcast and the annual meeting broadcasts. Seeing Tony and the others knocked my rose-petal glasses off and helped me see behind the curtain. They weren't magical men who talked with god anymore. They weren't fairytales casually mentioned in the WT on Sunday. They were real and they were horrible.
