| A receiver for three-dimensional televised images. |
The familiar use of the term to an authority figure helps to establish it in the mind of the reader. In the era before the hologram, this was the way that people visualized a three-dimension imaging system. You had to be able to walk around it to see all the details.

If this was really three-dimensional, would you be able to walk behind a newscaster and see the back of his head?

Curmudgeon and contrarian Jubal Harshaw also refers to it as a "babble box", which is probably an inside joke for sf fans, who recall the babble machine from H.G. Wells' 1899 novel When the Sleeper Wakes. (Thanks to R. Philip Reynolds for that observation in a comment on another item.)

Heinlein probably derived the idea for this from the 3D tank from EE 'Doc' Smith's 1934 story Triplanetary.

'The car surged and lifted, clearing its top by a negligible margin.'
Science fiction authors are serious about sleep, too.
