When I was a bit younger, a family member was always telling me that Betamax video recorders were going to win the Betamax versus VHS battle (I, of course, had a VHS machine). He had good reasons for his assumption, but in the end he was wrong. Here's how and why Beta recorders fell by the wayside (admittedly, I like this video in part because The Engineer Guy is from the University of Illinois, the college many family members, including an engineer, have graduated from).
For those of you not interested in this stuff, never fear. I'll go back to funny, sweet and touching things next time.
