A good report about the Australian mobile phone industry.
You will need to click on the image, but it shows the demographic profile of the survey audience since the first study in 2005. Interesting to see the way the original survey hardly included any oldies and how the current one is much more aligned to the Australian population age distribution.
I wish they would not cut-off the survey at '65+'. In fact they do not interview anybody older than 74.
Come on guys, wake up, the world out there is changing.
