Behind the scenes

 * The original 1965 serial The Chase does not identify Microsoft as the maker of the robots — indeed the company wasn't even established for another decade. This was later subject to a retcon in the aforementioned novel.
 * In the real world, Microsoft manufactured the Xbox, and released Windows Vista and Windows 7. These links, however, have yet to be made within the DWU.
 * PowerPoint is a computer application seen in PROSE: Iris Wildthyme and the Unholy Ghost, however it's not stated if it was made by Microsoft.
