If "embrace" means filling up the grandstands and providing a healthy TV audience for the broadcaster, then I think that's very doable. There won't be the drenched love fest that NASCAR has/had -- and you'll never reach NFL popularity -- but there appears to be a pretty big potential fan base. The races at Indy were always pretty well filled. ALMS and Rolex seem to be doing fairly well, and fans of those are likely to be aware of F1 if not fans of it. Same can probably be said of the club racing, autocrosser, etc population. Speed still shows F1 races live at the ass end of the morning, and big daddy Fox even shows some of the races, so there is TV money flowing in. We probably couldn't support the whole series itself (see: IRL), but as a one-or-two-off spectacle?
