When the British Heart Foundation revealed that it was running a solus ad break to warn viewers about the symptoms of a heart attack, more than a few eyebrows were raised.
But the brave strategy paid off; the two-minute 'Watch your own heart attack', which ran at 9.17pm on Sunday August 10 during the ITV1 drama 'Midsomer Murders', reached 6.5m viewers.
The one-off ad was designed to help viewers recognise the early symptoms of a heart attack, such as chest pain and nausea, so that they could react quickly and prevent the many needless deaths that currently occur.
Berkoff powerfully played out the symptoms with drama and medical accuracy. The campaign, conceived and created by Grey London, also included billboards, press and washroom ads, as well as online activity, up to its screening.
David Barker, head of communication at the BHF, says: "We are all familiar with the classic Hollywood heart attack, where you clutch your chest, fall over and die, but there are a range of symptoms and identifying these early is critical.
"We wanted to create a TV event. We have already had letters from people who said they saw the ad and it saved their life. We couldn't wish for better than that."
The Thinkbox Academy judges chose the ad as August's winner ahead of Land Rover's 'Location Scout' and 'History of Communications' from Carphone Warehouse.
