1. A system comprising:

  • at least one primary display device (PDD) configured with first instructions executable by at least one PDD processor;

    at least one companion device (CD) configured with second instructions executable by at least one CD processor;

    the first instructions being executable by the PDD processor to;

    receive an event trigger established by a particular actor or product or sound in content presented by the PDD as indicated by metadata in the content, or as indicated by recognition of demanded images, or as indicated by recognition of sounds presented on the PDD in a standalone mode and/or by uploading the images/sounds to a server for analysis, which sends analysis results back to the PDD;

    responsive to the event trigger, locate candidate companion screens that are in the same room as the PDD at least in part using a first signal;

    screen out candidate companion screens that are nearby the PDD but outside walls enclosing a space in which the PDD is disposed;

    provide at least a first candidate companion screen (FCCS) detected as being in the space with ancillary content related to the content presented on the PDD by linking the FCCS to a computer site associated with the content being presented on the PDD, the linking comprising providing a network address or link from the PDD to the FCCS selectable to access a computer network site on a home network, on the PDD itself, or on the Internet supplying the ancillary content, or the linking comprising sending a signal from the PDD to the FCCS to automatically access a particular network site and automatically commence downloading the ancillary content without any user action;

    wherein the CD comprises the FCCS, and the second instructions are executable by the CD processor to;

    responsive to receiving the first signal from the PDD, execute device discovery using a second signal having higher energy than the first signal, and present at least one user interface (UI) comprising an indication of the PDD that sent the first signal and not other devices detected during device discovery, the UI also comprising a first selector selectable to permit the CD to “

    throw”

    content to the PDD;

    responsive to selection of the first selector, send a message to the PDD soliciting use of the PDD as a companion screen to the CD.
