Instagram's new clickable 'Carousel' ad format

A New Way for Brands to Tell Stories on Instagram from Instagram on Vimeo.

This is pretty huge news, I think:  Instagram is launching a new ad unit, where advertisers can show multiple pics (slide from left to right), plus - crucially - a clickable link.

Until now Instagram has only allowed one clickable link, in the profile page, to try to deter spam accounts and comment spammers.  The new ad unit allows a clickable link to a web page - you can see how this could be very effective for advertisers.

This is likely to be US first, and then rolled out elsewhere later.
