In countries like the UK where 24mb/s is a common occurrence YES ipTV will be popular. The US has cable modems that runs at lightning speeds. Here we still fight to get a stable constant 4mb line. Anyway the content in SA is so not worth the money you have to cough up for the bandwidth.
I know there is a thread already but what is cable if not copper or fibre optic, the wiki page didn't shed much light on it either. Super5 is supposedly going to bring IPTV but it seems more likely that I will fall pregnant before they launch.
