Advertising Age: Conde Nast has struck a deal to post video on Snapchat from events such as the Teen Vogue Young Hollywood party and the Vanity Fair Oscar Party. Anyone who opens Snapchat around the time of one of Conde Nast’s events will be offered video in the platform’s Live Stories format, which curates footage from various users at a given location. Snapchat says it has 100 million unique daily active users and that 20 million people view a Live Story each day. Conde Nast’s Live Stories will be available for 24 hours each.
