A regional magazine, abOUT was founded in Buffalo, New York, in late 2003 by four partners, including veteran Canadian journalist Duane Booth. The first edition of the magazine was released on January 19, 2004. In 2006, Booth became majority shareholder when he acquired the shares of two of the business partners, and the magazine's operations were fully moved to Toronto at the same time.

In early versions of Netscape, any address beginning about: which wasn't recognised as a built-in command would simply result in the text after the colon being displayed. Similarly, in early versions of Internet Explorer, about: followed by a string of HTML (e.g. about:<em>hello world</em>) would render that string as though it was the source of the page - thus providing a similar (though more limited) facility to the defined by RFC 2397. Still other versions of Netscape would return various phrases in response to an unknown about: address, including "Whatchew talkin' 'bout, Willis?" (a catch phrase from the TV show Diff'rent Strokes) or "Homey don't play dat!" (from a recurring skit on the TV show In Living Color).
