What happens to MVPs when no one loves them anymore?

Minimum Viable Products are, by their nature, only meant to last for a limited amount of time. All of those products that didn’t get funded for continuous improvement, didn’t get iterated on, didn’t become full-fledged products, they all ended up like this skateboard. That’s better than full products being developed and abandoned, but I wonder what percentage of MVP’s get dropped, get developed, and more interestingly, just continue to operate without further improvements.
