No, but they were the first to sell an EV that made non-geeks' pulses quicken. The vehicles sold before that were more of the "eat your vegetables" variety, and thus doomed to be money-losing niche vehicles, useful only as arguments against the viability of the electric vehicle market.
Personally I think this is the key. They were the first manufacture of EVs to make one that young boys would want a poster of to put on their wall, or would want a Hot Wheels car of. Seriously my oldest child really wanted the poster of the Tesla roadster at his school's book fair and my youngest though the Tesla roadster Hot Wheels car was really cool looking.
Also I would say most of the previous EVs were less "eat your vegetables" and more 1970s space cadet category (who wants to buy a strange looking little car), but the Nissan Leaf I would put in eat your veggies category.
If all else fails, lower your standards.
