VideoTex companies were showing (and I think in at least two cases operating) prototype Videotex in 1981 and possibly earlier. At shows I attended back then, Cox Cable, AT&T, and other players were all showing prototype online advertizing and online commerce transactions. Both text and graphics were explicitly a part of the design. The prototypes displayed were live code and used both together.
I don't know of any prior art before then, but commerce on The Source, CompuServe, and Dialcom (to name three) was already going by then (just probably not with images).
