CNN founder didn't just create 24-hour news. He invented the always-on channel stack — and Korea's ATSC 3.0 transition is its newest test case.

The cable era's most consequential architect has died. Ted Turner, founder of CNN (Cable News Network) and the man who created the 24-hour news cycle, passed away on Wednesday at his home near Tallahassee, Florida. He was 87.

Family spokesman Phillip Evans confirmed the death. Turner had disclosed in 2018 that he was suffering from Lewy body dementia, a progressive brain disorder he later said had been mistaken for years as bipolar disorder.
