Staged to celebrate the completion of the Panama Canal, and drawing over 19 million visitors in only nine months, the Pan-Pacific International Expo rose like a literal jewel from the ashes of San Francisco's 1906 Earthquake and Fire.
A Century of Progress International Exposition was held in Chicago, Illinois from 1933 to 1934 to celebrate the city's centennial. The theme of the fair was technological innovation. Its motto was "Science Finds, Industry Applies, Man Conforms".
The 1939-40 New York World's Fair, located on the current site of Flushing Meadows-Corona Park, was one of the largest world's fairs of all time. The fair ran for two seasons and over 44 million people attended.
The Golden Gate International Exposition was held in San Francisco, California to celebrate the opening of the San Francisco-Oakland Bay Bridge and the Golden Gate Bridge. The exposition's first season ran from February 18, 1939 through October 29, 1939 and its second season was from May 25, 1940 through September 29, 1940.
The 1964/1965 New York World’s Fair, located on the current site of Flushing Meadows-Corona Park. The fair ran for two seasons and took place without sanctioning from the Bureau of International Expositions.
Expo 67 was held in Montreal, Quebec, Canada from April 27 to October 29, 1967. It was considered to be the most successful World's Fair of the 20th century, with over 50 million visitors and 62 nations participating.
You asked for it!
I can identify the gear, but it would be interesting to identify the source of each monitor image. If you could please send me a higher res scan, it might be possible to read talley lights / input IDs and see what's on the small monitors.
Anyway, starting with the upper row of monitors and gear, and going left to right:
Monitor showing telecine output of a western movie of some kind. In one of my personal slides, this image is a SMPTE resolution test pattern slide.
Monitor with color bar test signal. In one of my personal slides, this monitor has the "see yourself" image.
Monitor with tight shot of man - probably studio camera (?)
Two instruments: the wide short one is a vectorscope, used to check the color part of the composite signal;
the taller narrow one appears to be a waveform monitor, used to check the overall amplitude and details of the complete video signal. A high resolution scan of these two might reveal which signal they are currently measuring.
Two monitors with the same picture of a guitar player. One is probably a studio camera monitor or switcher "preview" and the other may be a "master" final output to the fair network.
Lower row of gear: multiple camera/telecine control units. I count seven, and I think there were three studio cameras, one see-yourself camera, and two telecines. So, not sure if there was another telecine, a flying spot slide scanner (which could be what was used for the RCA logo that was permanently displayed on a TV where you entered), or what. EACH of those control units is attached to a six-foot high rack of support electronics, totaling about $100,000 in 1964 dollars for each chain of camera, control/monitor panel, and support gear, or about $800,000 each in today's dollars.
The second control unit from the left is showing the western film on its monitor; the third from the left looks like it could be the "see yourself" camera. The ones on the right are too washed out and low res to guess, but are probably studio camera pictures we see up above.
The large central metal console is the switching and special effects unit. You see buttons to select sources and special effects, and the T-shaped fader handles that control the fades or wipes between sources. The left part appears to be an audio console with the square areas being VU meters (not sure). If that is audio, it would seem skimpy today, but was probably considered as luxurious as the video gear then.
It's strange that they seem to have something going on in the studio, but no-one is at the console. It's also possible there is nothing much going on in the studio and they have punched up the NBC network, or video tape.
At the extreme upper right you see a portion of one of the video tape machines, which also could be the source currently on one of the monitors.
I have a picture in which the color monitor just right of center has the RCA logo on it, and the operator at the console is looking in that direction, so that may indicate that this was the master. I also have a picture with duplicate images on the same two monitors that have duplicates here.
By the way, it appears there was someone standing between the second and third color monitors, who moved while the shutter was open, but the monitor images do not appear blurred. A bit puzzling, that.
I just noticed that CSPAN is running the entire CBS 1969 coverage. Tonight they aired an interview with President Johnson by Walter Cronkite.
PS: Did anyone notice that CNN did several heat wave related weather forecasts, today, from in front of the Unisphere with the fountains splashing? I saw two early this morning (Friday, July 19).
