Misplaced Generations

When a performer gets older, does the audience grow with them?

From a marketing perspective, it's a challenge to target a constant demographic when the variable at hand, such as age of the asset, evolves out of the current trends. Doing so would mean that you're adapting to the newer generations that mature every year to meet your fixed target market.

But what happens to that market as they grow older? What do they move on to? Are they more uninterested in the age of the asset itself, or is it something internal that disallows them to not be into that attractive "thing" anymore?

Even better, could it be the lack of desire to be associated with the younger, more immature demographic that is coming into the trend. Who would want to share an interest with such a juvenile crowd?
