Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A controlling device is identified that includes a display for presenting content to a user. An indication is received from an application running on the controlling device of an intent by the user to receive a first content item on a separate but co-located presentation device. Based on the first content item, additional content items are selected for simultaneous delivery on the controlling device while presenting the first content item on the co-located presentation device. The additional content items include interaction points that are configured to enable the user to interact with the additional content items, which are delivered to the controlling device. User input is received that is in the form of an interaction with an interaction point. The interaction is attributed to the presenting of the first content item. |
