The Guardian uses stats from the commercial tv research team, Thinkbox, to suggest that the BBC has lost 18% of tv viewers aged 16 to 34 in moving BBC3 online.
The BBC counters, saying BBC3 programmes available on demand now make up 11% of all catch-up requests, compared with 4% before the broadcast channel closed.
This percentage may stand still for a while. There are some 14.5m 16-34 year-olds in the UK. The student population is around 2.5m. From 1st September, those living away from home will need a full tv licence to watch BBC3 on demand. They can catch up with ITV2 and various C4 yoof offerings for nowt; they just have to remember - no live stuff.
