A dynamic user interface for previewing live content includes multiple tiles. Information for multiple pieces of live content available from a gallery is obtained, and this information is presented in the multiple tiles of the user interface in accordance with a current user interface layout. In accordance with one aspect, this current user interface layout changes automatically over time as the user interface is displayed. In accordance with another aspect, one or more of the multiple tiles is displayed in the user interface more prominently than the other tiles, and which information is to be displayed in the one or more tiles is based at least in part on a received fee.
