Instead they only investigate from individual consumer complaints
Ive not watched the vid, but from recollection most of ASA's complaints appear to come from other organisations especially when it comes to broadband.
BT/Virgin/Sky/TT etc are all at it and can't wait to jump on latest ads. They usually only get slapped wrists though and told not to run the ad again. Until they start fining I think the SPs will continue to push the boundaries.
The APA which I think is Canada's ASA
I've not been to the States recently so don't know if its still the same, but we used to go a lot and one of the things that always struck me is just how many adverts stretched the truth.
