A term meaning "in general circulation." Even though the quantity is still limited (everything is finite), a thing that is widely available can be easily obtained. This is an important milestone for many commercial products, books and software. It means that the general public now has access to the aforementioned goods. This marks a psychological milestone as well as a economic one: mentally, it makes the product's creators or supporters feel famous, and because the product is now easy to access, sales of the product could potentially skyrocket relatively quickly.
