from the C64 Wiki
During the Commodore 64's lifetime (between 1982 and 1993), total sales exceeded 22 million units.
Hardly 30 million, a mere 22+ million ! That's only 1 for every 3 people in the UK !
So it was POPULAR, not arguing about that, but commercial is based on money isn't it? and commodore ran out of money, so it failed, I mean if you are churning 22 million of them out for 10 years at $500+ a pop and you still manage to go bankrupt I wouldn't class it as a great sucess story, commercialy speaking.
It has an impressive list of achievements ( from the wiki )
best selling computer model of all time.
10,000 software titles
popularized the computer demo scene
a $460 mark up
but they still went bust.
Now you made me go and do more research.
Plus my car
was a commercial failure, I even lost money on that when I sold it only five years later, MX5 a complete commercial failure!
I've got to stop selling stuff.
