Audible continued its publishing endeavors in May 2011, when it launched Audiobook Creation Exchange (ACX), an online rights marketplace and production platform that connects narrators, producers and rights holders in order to create new audiobooks. The platform has been so successful that in 2012, Audible reported it had received more titles from ACX than from its top three audio providers combined. In March 2012, Audible launched the A-List Collection, a series showcasing Hollywood stars including Claire Danes, Colin Firth, Anne Hathaway, Dustin Hoffman, Samuel L. Jackson, Diane Keaton, Nicole Kidman, and Kate Winslet performing great works of literature. Firth's performance of Graham Greene's "The End of the Affair" was named Audiobook of the Year at the Audie Awards in 2013. Audible's efforts to make audiobook narration a mainstream art form extends to the narration workshops it offers at acting schools including Juilliard and Tisch School of the Arts; in 2013, the Audible's CEO speculated that the company was the largest single employer of actors in the New York area. In 2014, at Audible's headquarters' six recording studios, producers and voice actors create new audiobooks 16 hours a day, seven days a week.
