Chase Raz and Christopher Woodward are back for part two of "Tech Blunders". They'll discuss things that could have been big, but weren't. Like last week, the blunders reviewed all happened in the late 20th or early 21st century, but their specific reasons for failure were extremely varied. The selections on this week's--and last week's--lists are offered as food for thought for modern business people, product developers, and marketers to contemplate.
