Mark Stephens, known to millions of readers and viewers as Robert X. Cringely, was an American technology journalist, author and television host whose irreverent, personality-driven writing helped define how the world understood Silicon Valley. He died on October 3, 2026, in Charlottesville, Virginia, at the age of 73.
Stephens was born on January 28, 1953. His family obituary gives his birthplace as Cleveland, Ohio, and he grew up in Apple Creek, Ohio, the son of Ray and Lois Stephens. According to a 1998 Wired profile, his mother was a librarian and his father a labor union organizer, and before he turned 14 he had built two small airplanes with his father. As a teenager he won a scholarship to the Merchant Taylors' School near Liverpool in England, where he earned his pilot's licence through the school's compulsory military training. He then studied physics at the College of Wooster in Ohio, graduating in 1975, and worked briefly as a newspaper stringer covering conflict in Northern Ireland and Beirut.
By 1977 he had moved to California, arriving in Silicon Valley at the start of the personal computer boom. He worked with Steve Jobs in the earliest days of Apple and later said that when Jobs offered him shares as payment he held out for $6 an hour instead. He earned a master's degree in communication from Stanford University in 1979 and stayed on for doctoral work. That same year he served on the Public's Right to Information Task Force of the President's Commission on the Accident at Three Mile Island, and in 1980 he published the book Three Mile Island under his own name.
In 1987 Stephens became the third writer to take over InfoWorld's "Notes from the Field" industry column under the house pseudonym Robert X. Cringely, a name the magazine had originally used for a fictional staffer. Earlier Cringelys had lasted only briefly. Stephens kept the job for eight years and turned the byline into one of the best known in computing, mixing insider gossip, sharp analysis and open opinion. In 1992 he published Accidental Empires: How the Boys of Silicon Valley Make Their Millions, Battle Foreign Competition and Still Can't Get a Date, a bestselling, anecdotal history of the personal computer industry. Famously, he printed his own phone number in the book and took calls from readers.
InfoWorld dismissed him in 1995 after a financial disagreement, and its publisher IDG sued to stop him using the Cringely name. The case was settled out of court, allowing him to keep using the name as long as he did not write for competing computer magazines. He did, and he kept the name for the rest of his career.
In 1996 PBS broadcast Triumph of the Nerds: The Rise of Accidental Empires, a three-part documentary based on his book and hosted by Cringely. It featured candid interviews with Bill Gates, Steve Jobs, Steve Wozniak, Paul Allen and others, including Jobs's blunt claim that Microsoft made mediocre products. His full 1995 interview with Jobs was later rediscovered and released in 2012 as Steve Jobs: The Lost Interview. He followed with Nerds 2.0.1: A Brief History of the Internet in 1998, the PBS special Digital TV: A Cringely Crash Course, and Plane Crazy, a PBS series in which he tried to design and build an airplane in 30 days.
From the late 1990s until December 2008 he wrote the weekly online column I, Cringely for PBS, and in 2005 and 2006 he produced and hosted the internet television interview show NerdTV. From 2009 he published independently at cringely.com, where readers followed his annual technology predictions, his reporting on IBM that became the 2014 book The Decline and Fall of IBM: End of an American Icon?, and his own startup adventures, including the Mineserver project and the satellite launch venture Eldorado Space.
His later years brought hardship. In a 2020 column he described going blind and losing his home and business in a fire while raising three minor children. In a May 2026 post he wrote that he had suffered a heart attack and a stroke in July 2025, followed by ten weeks in hospital, and that his son Cole, who had taken over as architect of an AI legal writing startup during his recovery, died in his sleep on April 14, 2026, at the age of 21. "For now just know my heart is broken," he wrote.
Stephens died on October 3, 2026. A family friend reported on Hacker News that he died in his sleep; no cause of death was made public. His family's obituary described him as "brilliant, funny, opinionated, curious, generous, exasperating, and unforgettable." He was predeceased by his sons Chase and Cole and is survived by his wife, Mary Alyce, his sons Channing and Fallon, his brother Paul and his sister Ann. Fellow columnists credited him with proving that readers wanted tech writers with real personalities and points of view, and his documentaries remain among the most watched records of the people who built the personal computer and the internet.
