See? It's not that obvious even now, is it?

I saw this on TV twice, possibly on Discovery channel. A crowd
was celebrating the end of WWII in the street and the reason for
jubilation was displayed in giant scrolling text on the side of a
building. Certain factors prevented me from discerning the type
of display used - 1) the part showing the display was brief, 2)
it was an old B&W film, 3) delayed reaction on my part both times.
I've searched for it from time to time without success. It's
unlikely that the technology for a scrolling electronic display
existed then. So what was it? A banner?
BTW I love the photo of a sailor kissing a girl that day. I think
it's one of the great photos of all time.
as a far as I know the worlds first scrolling electronic sign was
invented
by the danish engineer and inventor Viggo Jensen and put into operation
in 1914, it was controlled using paper tape and mercury
this is from 1939

Ah, so the technology did exist then. Thanks. I still wish I could find
that particular clip, though.
Check this out, this is some high-quality _color_ film footage from NYC
in the mid-late 1930s!

Look at all this animated signage. State-of-the-art hi-tech stuff at the
time.
Amazing. Running lights and switched signs are one thing, running
text requires another level of ingenuity IMO.
No... we had movies. One frame at a time. We had blinking lights...
it's not to hard to imagine moving blinking lights.

How they did it might be interesting.
