Comcast is made up of three parts. The core cable business owns networks that provide television, internet access, and phone services to 65 million US homes and businesses, or nearly half of the country. The firm provides services to about half the locations in this territory. Comcast acquired NBCUniversal from General Electric in 2011. Following the spinoff of several cable networks, including CNBC, MSNBC, and USA, NBCU now consists of the NBC network, several local NBC affiliates, Bravo, the Peacock streaming platform, Universal Studios, and several theme parks. Finally, Sky, acquired in 2018, is a large television provider in the UK and Italy.

Regime-dependent
