Hartsfield-Jackson Atlanta International Airport (ATL) has been the world's busiest airport for over two decades — 93+ million passengers annually. Its ET location makes it the ideal domestic connection hub: flights to both coasts are manageable same-day roundtrips. Delta Air Lines, headquartered here, schedules its global network around Atlanta time.
Atlanta is the corporate capital of the Southeast: Coca-Cola, Home Depot, UPS, Delta, Southern Company, and NCR all headquarter here. The city is also the center of Black culture and business in America — home to Morehouse, Spelman, Clark Atlanta (the largest HBCU cluster), and the birthplace of Martin Luther King Jr.
CNN was founded in Atlanta in 1980 — the world's first 24-hour news network. Its headquarters at CNN Center operates on ET, and the 24-hour news cycle concept was born from the idea that news doesn't follow timezones.
