Thanks to Trendwatching.com for this concept and examples.

As Warhol predicted with "15 minutes of fame", hundreds of millions of individuals are craving immortality, or at least some public attention. Whether it's blogging, participating in Big Brother, having a character in a novel named after you, or adorning your car with personalized license plates, the masses want their names out there. This is where graffiti meets vanity to form GRAVANITY: an entire industry catering to the obsession of ordinary citizens wanting to leave 'something' behind in print, audio or imagery, preferably in the public domain. Consider it a 21st century version of university libraries and hospital wings being named after the rich ruling classes.

GRAVANITY offers a host of opportunities for entrepreneurs willing to (re)name their goods and services, however small, on behalf of eager customers. TRENDWATCHING.COM predicts museums selling sponsorships of even the smallest works of arts (or just the frames!), theatres offering GRAVANITY space on each seat, real estate developers auctioning off the rights to have apartment buildings and lobbies adorned with the names of middle-class families, and Domino's introducing pizzas named after cash-rich, attention-poor pizza lovers who will reveal their favourite toppings to the world. If it can have a name attached to or printed on it, it WILL sell!
