This is ridiculous. The infographic shows examples of 'successful' startups that have only been around for 2 years, then setting them side by side with 'failed' startups that took 5 years or more to fail.
And as someone else mentioned before, Zynga is far from a success story. It's one of the most memorable failures, if anything.
I'm sure the study provides very sensible results, but this infographic is a complete misrepresentation of it.
