This is one of the earliest forms of ASCII art, dating back to the early days of the 1960s minicomputers and teletypes. During the 1970s, it was popular in US malls to get a t-shirt with a photograph printed in ASCII art on it from an automated kiosk containing a computer, and London's Science Museum had a similar service to produce printed portraits. With the advent of the web, HTML and CSS, many ASCII conversion programs will now quantize to a full RGB colorspace, enabling colorized ASCII images.
