NBCUniversal Media, LLC (abbreviated as NBCU and doing business as simply NBCUniversal or Comcast NBCUniversal since 2013) is an American multinational mass media and entertainment conglomerate that is a subsidiary of Comcast and is headquartered at 30 Rockefeller Plaza in Midtown Manhattan in New York City.

NBCUniversal is primarily involved in the media and entertainment industry. The company is named for its two most significant divisions, the National Broadcasting Company (NBC) – one of the United States' Big Three television networks – and the major Hollywood film studio Universal Studios. It also has a significant presence in broadcasting through a portfolio of domestic and international properties, including USA, Syfy, Bravo, E!, Telemundo (Spanish), Universal Kids, the streaming service Peacock and ownership stakes in Snap and Vox Media. Via its Universal Destinations & Experiences division, NBCUniversal is also the third-largest operator of amusement parks in the world. Since 2018, its sister company under Comcast's control, Sky Group Limited, holds its media and telecommunication assets.

NBCUniversal was formed on May 11, 2004, beginning on November 8, 2004 as NBC Universal, Inc., with the merger of General Electric (GE)'s NBC with Vivendi Universal Entertainment's film and television subsidiary Universal Studios, after GE had acquired 80% of the subsidiary, giving Vivendi a 20% share of the new company. In 2011, Comcast attained 51% and thereby the control of newly reformed NBCUniversal, by purchasing shares from GE, while GE bought out Vivendi. Since 2013, the company has been a wholly owned subsidiary of Comcast, which bought GE's ownership stake.
