"Recent" publicity concerning TV (1930s)
 

I picked up this 20 page booklet on ebay. It apparently is a reprint of newspaper and magazine clips by the Shortwave and Television magazine.

It includes electronic and mechanical TV. Of particular interest is a number of clips that describe demonstrations of mechanical TV-telephone demonstrations held at various department stores, fairs, car dealers, etc. in various cities. One of the articles mentions that it was produced by the American Institute of Television of Chicago. It says the machines were first displayed in Germany.

More on ATI, the hardware, and its proprietor, Ulysses A. Sanabria, is on the earlytelevision.org site:

I suppose had WW2 not happened, we may have grown up on 441i video and AM for the sound... Though I think the FCC switched to 525i and FM in 1941.

Me thinks it was 525i and AM sound in 1939... FM was part of the 1941 change...

this site claims FM sound was adopted before 525i, and 525i was the last modification made by the first NTSC, which was standardized in 1941:

I think I have read the same elsewhere, can't put my hands on it now.

Very cool find! On page two there is a Television-Telphone ticket from Stix, Baer, & Fuller. That was a department store in downtown St. Louis. I'll have to see if I can find out more about it.
