Chris Anderson Editor of WIRED Technology's Long Tail on: TedTalks Chris Anderson, the editor of WIRED (not to be confused with the curator of TED, who has the same name), explores the four key stages of any viable technology: setting the right price, gaining market share, displacing an established technology and, finally, becoming ubiquitous. To demonstrate this trajectory, Anderson explores the evolution of the DVD player as it passes through each of these four tipping points, then offers specific examples of current trends in technology -- ranging from DNA sequencing to the hybrid -- to illustrate each stage of the game.
