Did the golden era of Web video come and go with 2006? Videogum says yes, citing it as the year of some of the best and weirdest viral videos, plus The Show With Ze Frank, Ask a Ninja, G.I. Joe's "Porkchop Sandwich," and some fantastic mash-ups. Their theory: "2006 was, of course, the last year in which viral videos were the exclusive work of amateurs, before corporate America decided to try their hand at it. Blame Pepsi." [Videogum]
