A plethora of brands once again engaged attendees at the SXSW conference and festival this year, which included 10 days of content, activities and events geared toward professionals in the tech, music and film industries. And Event Marketer staffers were on the ground from March 13-18 to take in the experiential activations firsthand. Check out this photo gallery of 18 brand engagements, from AppleTV’s retro Tetris experience to Peacock’s roaming nun activation to C4 Energy’s DIY creator lab for graffiti-style streetwear.
