Comcast CMCSA

Comcast operates NBCUniversal (Universal Pictures, NBC, MSNBC, E!), Peacock streaming, Sky (European TV and broadband), and Xfinity (the largest US cable broadband provider with 32M+ customers). Its broadband duopoly position in US markets - often the only high-speed alternative to AT&T - gives it pricing power. Comcast is the infrastructure and content company that most Americans can't escape.
