The web economy has grown rapidly in the last decade. Online businesses have several key features that are important for understanding the pro-competitive and anti-competitive strategies they may engage in. The two-sided markets literature helps elucidate many of these strategies. It also provides guidance for the antitrust analysis of market definition and exclusionary practices for web-based businesses.
