That is also my recollection. I can't remember when the first work on
dither was done, but I think it was produced a long time ago. Hence there
really isn't much excuse for someone writing magazine articles like NKs not
to understand it. I was certainly reading about such matters long ago.

Dither was certainly used in the BBC thirteen channel PCM coders used
for the BBC radio distribution network in 1972(?)

In which case the speculation I have occasionally seen on the web that
some early CDs lacked dither is probably inaccurate.
