The young guys who think Chris is Mr O also don't watch the Arnold Classic, pro shows, or even the O for that matter so it isn't as if the IFBB is hemorrhaging money in that regards. You are talking about these new gym fags who only at most started lifting in 2021 and have no intention of actually following bodybuilding but rather following Chris and claiming they are a fan of bodybuilding while only being able to name Coleman, Bumstead, Levrone, Platz, Mentzer, and maybe Ramy. As far as the most mainstream appeal it is more that Chris has the most mainstream appeal, not classic, if anything mens physique has more appeal than classic as the bodies there are on the cusp of being considered too much whereas with classic and open the general population will say too much.
