Virgin Media has been running its "FASTER THAN A SPEEDING" marketing campaign for a while, most people will at some point have seen the large billboard ads featuring a stylised bullet hole. The Advertising Standards Authority received ten complaints from people who had received a mailshot version of the above, with some complainants feeling that 'bullet hole' in the envelope was inappropriate.
The full adjudication can be read here. The ASA did not uphold the complaints that the mailing might cause offence or distress, but did warn Virgin Media about the lack of indication on the outside of the envelope that this was marketing material.
The various 'fibre optic' claims made in Virgin Media advertising received an OK from the ASA back in February 2008 even though their cable network is actually fibre to a cabinet within 1km of customers homes, and then co-ax cabling direct to the home, or possibly another cabinet. Once services like H2O start advertising and sites like Ebbsfleet Valley go online, which will be fibre all the way to inside the home are available one presumes Virgin Media will have to reign in its claims.
