Take-Two Interactive, publisher of — among other things — Grand Theft Auto IV, is taking legal action against the Chicago Transit Authority regarding an issue with an advertising campaign. Apparently the Transit Authority, who works with Titan Worldwide Chicago for advertising, prematurely pulled ads that featured GTA IV for an unconfirmed reason and thus infringed on Take-Two’s free-speech rights. As a result, Take-Two is suing the Chicago Transit Authority and is asking that a federal judge stop the CTA from pulling the GTA ads. The lawsuit was filed in Manhattan.
