Holovision was a type of communication medium, presumably an advanced version of television presenting three-dimensional holographic imagery.

Orions invented holovision technology and entertainment during their New Days. (FASA RPG module: The Orions: Book of Common Knowledge)

A holovision receiver was available in the living quarters of the Agro III agronomy station in the 2040s. (TOS novel: Strangers from the Sky)
