The 2013 South by Southwest music, film, and technology festival wrapped March 17, with an estimated 150,000 people turning out for all or part of the 10-day event. With big names like Justin Timberlake and Prince appearing alongside a tech-savvy crowd of influencers, the fast-growing Texas event has become a veritable playground for corporate marketers, continuing to attract experiential efforts from a diverse mix of brands. This year saw companies like Warner Brothers Television join the slew of SXSW parties and promotions, while returning hosts like The Fader and Filter beefed up their activations with online extensions.
Here's a look at the most interesting brand activations and events from this year's festival.
