Origin & History of ISO
The International Organization for Standardization was founded in 1947. Its goal was to create common standards that could be used internationally to improve quality, safety, and compatibility.
Interestingly, the name “ISO” is not an acronym. The organization chose “ISO” from the Greek word “isos,” which means “equal.”
Meanwhile, the texting version of ISO (“In Search Of”) emerged much later through internet forums, classified ads, and online communities. As social media grew, the abbreviation became a quick way to signal that someone was looking for something.
Today, both meanings are widely recognized depending on the situation.
