I was sad to find out the other day that one of the best toy ads of all time (that I wrote about briefly a while ago) was only ever shown about 5 times in the UK.
Apparently the client didn't like it as there were no images of children actually playing with the toy...
Such a wonderful ad, showing the huge possibilities of the product in a witty and engaging way; and the client killed it.
Happily its such a good ad that it is still remembered even though it was hardly seen at the time.
