A holographic billboard, or holobillboard, was an animated billboard in 2015 that was displayed as a holographic projection.
An opinion poll titled 3D BILLBOARDS: FREE SPEECH OR TRAFFIC HAZARDS? was announced in a box-out in the top right-hand corner of the October 22, 2015 issue of USA Today, which asked the question Was billboard responsible for 2 traffic fatalities?
- We are just entering the midpoint between the billboards and holobillboards with digital billboards: giant flat-screens that rotate different advertisements every thirty seconds. Also, images can be projected onto partially visible gases to produce the effect of a "holobillboard". Miniature USB versions can be purchased in the form of Heliodisplays.
