"JSON is the world's best-loved data interchange format," Crockford said in an video interview with the IEEE's Computer magazine published in March. "I discovered it in 2001. I don't claim to have invented it, because it already existed in nature."
When he encountered others' reluctance to use JSON because it wasn't a standard, he decided to take care of the problem: "I bought JSON.org, put up a Web page, and sort of declared, 'It's a standard.' That's it. I didn't go around trying to convince industry and government that's what they should do. I just put up a one-page Web site, and over the years, people discovered it."
He describes one advantage of JSON over an alternative, XML (Extensible Markup Language), that was the subject of much hype in years past. But to Crockford, XML data sent from a server is hampered by the fact that it must be processed to be useful. "Why can't you just give it to me in a form where I know what it is and I can use it immediately? That was the main benefit of JSON."
