"Nearly 190 million people tuned in for the inaugural season for Formula E,"

More people will have watched 2017 Lemans 24, which ran yesterday and Saturday, than all those who watched the entire 2016 Formula E season. F1 draws 700M - 800M viewers annually. Formula E is a spec series with a common chassis (Dallara) and a FIA mandated limit on HP (270) and speed (225Kph). Its hardly the future. I saw part of the Formula E race is Miami in March 2015, and while it was interesting to watch, It was no better than GP3 and no where near F1. Formula E will live or die based on the quality of the racing - not that it's electric.
