CHICAGO Billed as the largest in the nation, the 10-day Chicago Auto show opened at McCormick Place on Friday and runs through Sunday. The Chicago Automobile Trade Association produces the show, which is spread over 1.2 million square feet of the convention center. To stand out in the vast space, exhibitors relied on everything from game board-inspired test tracks (for Toyota) to button-making stations (Chevrolet).
This year's exhibitors also leaned on social media to help spread their messages from the trade show floor to the Web, using tropes such as photo stations that let guests post branded pictures on Facebook and Twitter. Here's a look at how Hyundai, Cadillac, Lincoln, and other major auto makers stood out and used social media on the trade show floor.
