“By his own rough estimate, John Coleman has performed more than a quarter million weathercasts. It is not a stretch to say that he is largely responsible for the shape of the modern weather report. As the first weatherman on ABC’s Good Morning America in the late 1970s and early ’80s, Coleman pioneered the use of the onscreen satellite technology and computer graphics that are now standard nearly everywhere. In 1982, chafing at the limitations of his daily slot on GMA, Coleman used his spare time—and media mogul Frank Batten’s money—to launch The Weather Channel. The idea seemed quixotic then, and his tenure as president ended a year later after an acrimonious split with Batten. But time proved Coleman to be something of a genius—the channel was turning a profit within four years, and by the time NBC-Universal bought it in 2008 it had 85 million viewers and a $3.5 billion price tag.
Those were the first two acts of Coleman’s career. On a Sunday night in early November 2007, Coleman sat down at his home computer and started to write the 967 words that would launch the third. “It is the greatest scam in history,” he began. “I am amazed, appalled and highly offended by it.
