This is not really a dig at BT this time, honest. More about the whole perception of "internet speed" that the public, and clearly advertisers, have...
The advert is a halloween party where they are trying to download music (presumably legally) but the internet is "unlimited, but slow". They are unable to play *any* music for the party, having apparently spent ages preparing the play list.
Apart from the fact you would have downloading said "play list" when preparing it, and so not be relying on the Internet, what puzzles me is that even a high data rate audio file is around 300Kbps, which would be incredibly slow for an internet connection. Under half a percent of the BT based broadband lines we operate run at 250Kbps or less, which is enough for a more normal MP3 file, which can be played as soon as you start downloading it. Indeed, the BRAS rate below that, 135K, which is still just about fast enough, is considered to be a fault.
So what sort of "unlimited, but slow" internet connection is it that they are referring to?
Is there really any UK commercial Internet service too slow to download an MP3 faster than you can play it? Apart from dialup?
What am I missing here?
