Featured in a 1935 issue of awesome futurist-comic-book-slash-science-mag Modern Mechanix, the Notificator is almost certainly the world’s first Twitter client.
According to the article, the Notificator was placed in train stations—the depression-era equivalent of the internet, apparently—so that travelers could post ephemeral message for friends, families or passers-by.
I like to imagine 1935 Twitter as more charming and erudite than the 2009 Twitter, but I’m pretty sure it just had more messages about trains. [Infomark via AdamCrowe via Digg]
