25 years ago I heard about this program from a USENET newsgroup called Mosaic. I downloaded and installed it. As they say: Mind. Blown. All the pages had a grey background. The images would download one by one, and you could see each line of pixels loading. A later version would download the pictures simultaneously.
I read about Mosaic in a little blurb in a print publication, so I checked it out and it was a-mazing. I did a bit of random surfing and before too long stumbled into a particularly yucky subculture. That was my first inkling of the memetic future to come. It’s been double rainbows ever since.
