Another set of figures in the report lend weight to Prensky's emphasis on the generational divide in his natives/immigrants/dinosaurs theory:
The chart shows that a far lower percentage of older sections of the population are using the internet and also that a sizeable proportion amongst that group have tried and decided, cheers no thanks.
Finally the report also gives some raw data on usage of online tv and radio. The trend here clearly shows that participation is widening, but also that the rate of growth appears to be slowing. This perhaps hints at as yet unreached sections of TV and radio audiences, who are either economically disenfranchised from the digital revolution or simply satisfied with traditional forms of distribution.
