It looks as though in the UK therefore, teletext has been the victim of
the runaway success[1] of MHEG5.

[1] In the sense that it is almost, but not quite entirely, completely
unusable, in the same way that DAB is almost, but not entirely
unlistenable. Fortunately, FM and Digital telly are catching up and will
soon have achieved the same technical quality.

I guess the other comparison is that the only way they can make
everyone use DAB is to switch off FM (which they're not going to do
for a long time, whatever anyone says). The only way they can make
everyone use MHEG5 is to switch off teletext.

It would be nice (in fact, it should be a design goal) that new
systems should so much better than what they replace that people
desert the old system for the new. The old system should be switched
off because no one wants or needs it anymore, not simply to force
people onto the nwe system!

(Mind you, I can talk high mindedly about other people's work like
this - I wouldn't necessarily apply this approach in my work - real
world commercial considerations etc!)
