One of the things that I love about working with a group like Global Recordings Network (GRN) is there ability to think outside the Box. Their answer to the above question is to use the same means to communicate important information that 2/3rds of the world use... Language.
Whist everybody in the affluent world insist on teaching the world to read they are out there talking to people in there own language and their own dialect.
GRN have done way more than produce gospel messages they have even been commissioned to produce health messages by native governments.
But this video is about what there main emphasis is and although it is a pretty basic production. I thought that it was well worth watching.
