Remeber the slap on the wirsts from the ASA?
"'Now from Virgin Media, you could say goodbye to buffering with superfast fibre-optic broadband' "
Their defence was:
"Virgin Media had defended the ad by stating that the term "buffering" had a less technical meaning for punters who, it claimed, often link it to service interruptions or delays in streaming content. The telco also stated that, by using the word "could", the advert was clearly "conditional"."
