AT&T

AT&T creates value by building and operating communications infrastructure, then monetising that infrastructure through recurring access fees, managed service contracts and hardware attachment sales. In consumer markets it sells mobile and broadband subscriptions, often bundled with devices and account-management apps. In business and government markets it sells connectivity, networking, security, IoT and private network solutions under contract and managed-service arrangements.

AT&T is a US telecommunications operator providing consumer wireless plans, fibre broadband, business networking, IoT connectivity, private 5G and public-safety communications services. Its core business is selling recurring connectivity and managed network services to households, enterprises, government agencies and first responders, with additional revenue from device sales, installation and bundled service packages.

The company operates a broad national communications infrastructure and commercialises it across retail and enterprise channels. While AT&T previously expanded into media through acquisitions such as Time Warner, the WarnerMedia transaction closed in 2022, so the company should be understood primarily as a connectivity and communications infrastructure provider rather than a pure media or adtech business.
