Famous snack brand Pringles came up with this amazing at that time idea to put a whole long conversation into their banner. And to make it interesting and interactive users needed to click on the banner to discover every new line of it. Believe it or not, some people spend ridiculously long period of time playing with the banner, which obviously brought some good campaign results to Pringles. Brand exposure has been quite effective and the word of mouth spread rapidly among blogs and other creatives, which made this campaign stand out even more. Have a look at the campaign video and see if you can make something out of this campaign nowadays.
Someone once said, that every new good idea is in fact a re-designed good old one. So here is a good oldie for your inspiration.
