Video manipulation have been instances when this technology was used during political campaigns. The proof-of-principle software "Face2Face" was developed at Stanford University. Such advanced video manipulation must be ranked alongside and beyond previous examples of deep fakes. The concept of manipulating video can be traced back as far as the 1950s, when the 2 inch Quadruplex tape used in videotape recorders would be manually cut and spliced. After being coated with ferrofluid, the two ends of tape that were to be joined were painted with a mixture of iron filings and carbon tetrachloride, a toxic and carcinogenic compound to make the tracks
Video Floppy recorders & players were also used by television stations and video production studios as a still-store system for stills & graphics for use in a television production, or for on-air slides used for station identification or during technical difficulties (such as a "Please Stand By" still). A similar sized disk was also used by the Zenith Minisport laptop computer from 1989, digitally formatted for data storage. The Minisport could store up to 793 KB of information on 2-inch LT format disks called LT-1. Video floppy and LT-1 are not compatible, so media can not be interchanged between drives using video
