Traditionally social media platforms offered free service to users. The recent implementation of the pay-for-subscription model by some social media platforms motivated us to examine the equilibrium conditions under which the platforms can charge users. We model price competition between two horizontally differentiated platforms that can charge both the advertisers and users. The main results are: (i) Sufficiently strong platform preferences of the users enable the platforms to charge the users when they singlehome; (ii) Independent of parameter conditions, platforms can charge the users by allowing them to multihome while imposing singlehoming on advertisers
