Abstract: In one embodiment, a method for presenting alternate content during a channel change on a video content playing device includes: receiving a viewer's request to tune to a particular channel, retrieving tuning context data from a memory of the video content playing device, where the tuning context data is indicative of a context in which the viewer tunes to the particular channel, processing the tuning context data using a channel function associated with the particular channel to identify alternate content likely to be of interest to a viewer of the particular channel, identifying a network address for the alternate content associated with the particular channel in accordance with a result of the processing, retrieving the alternate content according to the network address, and presenting the alternate content on the video content playing device before presenting the program currently being broadcast on the particular channel.
