"The average person is exposed to 3000 advertising messages a day"

The social media experts over at Nixon McInnes (client of ours at Hotwire) have posted up a set of slides they've recommended on what is social media. The slides are a great backgrounder, and have some good stats that show the impact of traditional advertising against the reach of social media. Have a flick through if you like fast facts, like:

"Only 18% of TV ad campaigns generate positive ROI"

"The average person is exposed to 3000 advertising messages a day"

"36% of people think more positively of companies who have blogs"

Here's the slideshare in full. Thanks to Tom at Nixon McInnes for posting it originally.
