Snapchat Plans Big Pitch for Cannes Ad Festival

Bloomberg: This time last year, Snapchat was the hot new thing in social-media advertising — except that brands couldn’t tell if the promotions actually worked. Next week in France, at the Cannes Lions gathering of advertising executives, Snapchat will make the case that it now has many more ways to show return on investment. In the past 12 months, the company has done 10 partnerships with outside firms that can vouch for and measure the effectiveness of its ads.
