Abstract: This disclosure describes, in part, techniques for providing add-ons associated with network applications. For instance, a user may be controlling an application that is executing on a remote system using a control device and a display device. While the application is executing, the remote system may send user interface data to the display device, where the user interface data represents a user interface that includes add-ons that may be acquired for the application. If the user selects an add-on, the display device may communicate with a payment system in order to acquire the add-on. The remote system may then determine that the user acquired the add-on using data received from the display device and/or data received from a management system associated with the application. As such, the remote system may enable the add-on for the user within the application.
