I have been writing about consumer electronics for four decades, including news, reviews, analysis and history for a wide variety of consumer, niche and trade outlets. For the Consumer Technology Association (CTA), I annually update the industry's history and write the official biographies of the CTA Hall of Fame inductees. Aside from writing about consumer technology for a variety of consumer, tech and trade publications, I write a blog and do market research for Digital Technology Consulting. In the non-tech world, I have written "Bums No More: The Championship Season of the 1955 Brooklyn Dodgers" and "The Rules of Neighborhood Poker According to Hoyle."
