Background
WGBH is a PBS affiliate located in Boston, Massachusetts and was first aired on May 2, 1955 (though they never had a logo until 1972). The network is owned by the WGBH Educational Foundation.

1st Logo (January 3, 1972-September 1977)
Nicknames : "Zooming WGBH", "WGBH of Doom", "Zooming Letters (of Doom)"

Logo : Against a dark green background, the letters WGBH in yellow in a generic Helvetica font quickly zoom back, away from the viewer to the vanishing point. Then the word "Boston," also in yellow, zooms forward really fast, taking up the whole screen and creating a yellow background. And finally, the word "Presents" zooms forward at a fast pace, in dark green.

Variants : FX/SFX : The zooming of the words.
 * A black & white version first appeared on March 3, 1974. In this one, "WGBH" and "Boston" are both black, and "Presents" is white. This can be seen on very early episodes of NOVA.
 * On early episodes of NOVA, sometimes "Presents" would zoom forward as always, but superimposed against the opening cinematic.
 * On The French Chef, the logo is superimposed over a slanted flag of France against a blue BG, animation and all.
 * On season 3 of NOVA, everything that is supposed to be green in the logo is blue.
 * A brown and beige version exists.

Cheesy Factor : Simple animation. Additionally, The French Chef variant with the transition from Boston to Presents looks awkward: the Boston moves upward to not fill the screen in this one. And the unmusical "music" is even worse...

Music/Sounds : ...which consists of a choppy, UFO-like synth that ascends and descends several times, followed by a rising Moog violin stinger.

Music/Sounds Variant : The jingle is often sometimes played at a slower speed. Sometimes, the B&W version of this logo has a higher pitch.

Availability : Extremely rare, as programming from this era is usually no longer rerun. Tape-trading is the only way to see it, or you could find this logo on older WGBH programming, assuming it isn't plastered with a later logo. You might find this on old tapes of The French Chef, 1972's Z'oom, Evening at Pops, The Victory Garden and/or Nova episodes from the era.The'French Chef variant also showed up when WGBH-2 in Boston, MA had a marathon of old episodes ofThe French Chefon Christmas day, 2011. Tape-Trading is also another you can find this logo.

Scare Factor : High to nightmare. The high-contrast colors, extreme "V of Doom"-style zoom-ins, and that eerie synth music would have been sure to unnerve many people. Especially for those who aren't used to it.
