This is a rare rip of a sales presentation of the AT&T ARIEL system on analog LaserDisc. This system was developed for Walt Disney's EPCOT Center and used in the WorldKey Information kiosks. ARIEL/WorldKey was an interactive computer system that integrated full motion video, two-way video chat, an early form of touchscreen, and a mainframe backend to retrieve and present information. This preceded the World Wide Web by a decade or so.

After the launch of WorldKey, AT&T attempted to commercialize the technology to businesses and retail stores. There are a lot more details about the history of this video on the YouTube page.
