Oliver is currently a Principal at Bloomberg Associates, a philanthropic consultancy firm founded by Michael Bloomberg to provide advice and long-term solutions to cities worldwide. She also oversees film, television and digital media projects for Bloomberg Philanthropies, the charitable foundation of former New York City Mayor Michael Bloomberg.On August 1, 2002, Oliver was appointed by New York City Mayor Michael Bloomberg as the Commissioner of The New York City Mayor's Office of Film, Theatre and Broadcasting, which facilitates all aspects of film, television and commercial production in New York City, coordinating on-location filming, liaising with the community and promoting the City as an entertainment capital. Oliver was the main liaison between the Mayor's Office and Hollywood and aimed "to make filmmakers and production companies happy to return to New York."In 2013, Oliver and Mayor Bloomberg were featured on the cover of Variety and were credited for their role in "revitalizing the city's entertainment sector." An economic impact study released by the Boston Consulting Group in 2012 found that New York City's entertainment industry during Oliver's tenure as film commissioner had grown to account for a $7.1 billion annual direct spend in New York City, an increase of $2 billion since 2002, and that the local industry created 30,000 jobs in New York City since 2004, growing to employ 130,000 people. 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 NYC Media. In July 2010, Oliver became the commissioner of the Mayor's Office of Media and Entertainment, the city agency that includes the Mayor's Office of Film, Theatre and Broadcasting, NYC Media, and NYC Digital.
