AM New York noted that: "New York's film and TV industry is stronger than it has ever been, pumping $7.1 billion into the local economy in 2011 and bringing in some $60 billion over the last decade."  After Bloomberg announced that former president and co-founder of NYC Media Group Arick Wierson was returning to the private sector, Bloomberg named Oliver as the incoming president of NYC Media and general manager of NYCTV.
