Etymology
'stereogram' originates from Greek, specifically from the combining form 'stereo-' from 'stereós' meaning 'solid' or 'three-dimensional' and '-gram' from 'gramma' meaning 'something written or drawn'.
'stereogram' was formed in English in the 19th century from the Greek elements; it is related to terms like 'stereoscope' and 'stereograph' used in the development of stereoscopic photography. In the late 20th century the term was extended to include single-image autostereograms (popularized as 'Magic Eye' images).
Initially it referred chiefly to stereoscopic pairs or images viewed with a stereoscope; over time its use broadened to include single-image autostereograms that create a 3D illusion without separate image pairs.
