At least a band like Aerosmith successfully reintroduced themselves to multiple generations in both the 80s and 90s after breaking out in the 70s. Bon Jovi is living on his past.. not the present... just like Bruce (IMO).
Sorry, and really, this isn't meant as an insult, but that one sentence right there shows that you have absolutely no idea what you are talking about. If there's one thing Bon Jovi has become known for it's having fans that stretch across generations.
As for "living on his past" (first, it would be "their", not "his". Bon Jovi is a band.)

If you insist, I'll be more than happy to post the sales numbers for each individual album. And while their 3rd album is still their biggest seller, at the end of the 80's they had sold 25 million albums. By the end of the 90's, they had sold 65 million albums. By the end of the 2000's, they had sold 130 million albums. Do the math.
Edit: I'm not a huge fan of Bruce's either, but you're wrong about him too.
