I was 10 years old when dad bought the 1st (and only one) Betamax at home.
The Betamax died because Hollywood and movie makers (other say Porn movies producers) were pushing for a 1hr+ format, which VHS was able to provide. The VHS quality (as per some experts and online sources) was not as good as Betamax but the big advantage of the long lasting recording mode moved the scale on VHS favors; Sony continued pushing for quality and not long lasting recording option, at the end, people opted for VHS condemning the Beta format to dust and oblivion.
I just remember that rewinding the freaking movie was a pain! lol ... and the Betamax heads got dirty really easy and found myself cleaning those with alcohol and paper all the time (my 1st incursion into computers and electronic devices )
