38. eBay

You used to have to spend most of a Thursday afternoon calling various retail establishments and schlepping around town if you were looking to buy an F18 or a 45-million-year old aphid fossil,but no more. eBay was already a juggernaut as the decade kicked off, but in the Aughts it became a bona fide cultural phenomenon—and we're not just saying that so they'll remove those nasty comments toejamaficionado_31 left about us (although it'd be awful nice if they did).

In 2005, a partially eaten, 10-year-old grilled cheese sandwich bearing the image of the Virgin Mary sold for $28,000. And it could've sold for $28,001 if those jerks had just extended the auction five fucking minutes until we got home from church.
