Twitter has started to "monetise" its presence in the Social Media marketplace.
It has launched it's advertisng platform today which will allow businesses to place their own adverts into the stream of Twitter "tweets".
Among the initial customers are Virgin Atlantic and Starbucks.
When the ads appear amongst "tweets" they look like the image below. The marketing idea here is that twitterers will see the ad, click on it and in this case bring in a reusable coffee mug rather than a paper one and America is saved.
