Hours of Operation
As the first truly modern media company, AT&T has been changing the way people live, work and play for the past 144 years. It started with Alexander Graham Bell’s telephone. Since then, our legacy of innovation has included the invention of the transistor – the building block of today’s digital world – as well as the solar cell, the communications satellite, and machine learning.
Throughout its history, AT&T has reinvented itself time and time again – most recently adding WarnerMedia to reshape the world of technology, media, and telecommunications. Our two companies are no strangers to making history together. In the 1920s, AT&T built the technology to add sound to motion pictures, which Warner Bros. then used to create the first talking picture.
