Comcast sells internet, cable TV, mobile phone service, and owns NBCUniversal's TV channels, movies, and theme parks.
Comcast runs two big businesses under one roof, and they are very different animals. The first is connectivity: it sells internet, cable TV, and mobile phone service to homes and businesses, mostly in the United States, and it also runs the Sky brand in Europe. The second is content and experiences: through NBCUniversal, it owns TV channels like NBC and Bravo, the Peacock streaming service, Universal movies, and theme parks like Universal Studios. Roughly half the money comes from the connectivity side, and the other half from the content side.
Think of it as a landlord and a movie studio sharing a bank account. The landlord part—broadband and wireless—is the steady moneymaker. People need internet the way they need electricity, so they pay every month, and that recurring bill is the company's cash machine. The content part is more like a roller coaster: a hit movie or a sold-out theme park brings in a lot, but costs are huge and audiences can be fickle. Peacock, the streaming bet, is growing subscribers but has lost billions so far, and theme parks have been a bright spot with strong attendance and spending. Comcast competes with phone companies for internet, with streaming services for eyeballs, and with other studios for box office dollars.
Comcast started in 1963 as a small cable TV operator in Mississippi, and grew by buying other cable systems over decades. Its biggest turning point was buying NBCUniversal in 2011, which turned a cable company into a media giant. More recently it launched Peacock in 2020, and it has been spending heavily to grow that streaming business while broadband subscriber growth has slowed. The company throws off a lot of cash, which it uses for dividends, buying back its own stock, paying down debt, and investing in its networks and parks. The main risks are cord-cutting—people dropping cable TV—and tough competition from fiber and fixed wireless internet.
