Magazines and social networks operate in two-sided markets with network effects. Social media offer an ideal platform for word-of-mouth marketing that uses peer recommendations to read magazines. Theoretical and empirical studies of social networks identify the potential risks and rewards from using social media to market magazines. These risks and rewards are used to develop social media marketing guidelines that include recommendations for measuring marketing effectiveness. The recommendations include effective tools and tactics that can be used to attract more readers, thereby increasing the magazine's circulation and value.
