November 7, 2004 Oh no, we missed another birthday. This time it was the tenth birthday of the humble banner advert. On October 25, 1994 the first banner advert appeared on HotWired. Interestingly, it did not make news and the whole world missed it, probably because it seems to have been around longer than that. And whereas the fledgling industry of 1994 had trouble explaining what the internet was, the internet will account for 3.5% of global advertising expenditure in 2004. The AT&T advert's slogan was "Have you ever clicked your mouse right HERE?" and the advert was created in the 468 x 60 pixel format because it suited the site's layout.
