New article on Pallophotophone says "(also known as the RCA Photophone)" - so apparently 2 articles on same topic. PamD ( talk) 22:06, 4 June 2010 (UTC)
PeterH5322 has included text to the effect that Kodak were working on dual-languge, rather than stereo, optical tracks. Yet the paper I have, by R.E. Uhlig dated April 1973 and the one I cite in the text refers to stereo and only stereo, there is no mention of dual-language operation. Nor can I find any references anywhere to Kodak being interested in dual-language operation. I'd be interested in seeing any sources that support the notion of Kodak being interested in dual-language optical tracks.

The article's claim today :
is probably not correct. I was unable to check the cited source for that para. However on May 21 1958 the NYTimes said:
I was unable today to pin down when it -was- acquired. But Litton Westrex -did- exist by Jan. 1 1961 according to Physics Today. So it -had been- acquired by late 1960.
What exactly eventually happened to Westrex is even more complicated (at some point it wound up in Hong Kong?) ... but then so was Litton's fate. Twang ( talk) 02:34, 4 December 2020 (UTC)
