Multihoming occurs when users engage in similar types of interactions on more than one platform. A freelance professional who presents his credentials on two or more service marketing platforms, a music fan who downloads, stores, and shares tunes on more than one music site, and a driver who solicits rides through both Uber and Lyft all illustrate the phenomenon of multihoming. Platform businesses seek to discourage multihoming, since it facilitates switching—when a user abandons one platform in favor of another. Limiting multihoming is a cardinal competitive tactic for platforms.
