Billion

:For the modem manufacturer, see Billion (company).

10^⁹

In the late 17th century a change was made in the way of writing large numbers. Numbers had been separated into groups of six digits, but at this time the modern grouping of three digits came into use. As a result, a minority of Italian and French scientists began using the word "billion" to mean 109 (one thousand million, or 1 000 000 000), and correspondingly redefined trillion and higher numbers to mean powers of one thousand rather than one million. This is known in French as the échelle courte ("short scale") and is now officially used by English-speaking countries, as well as Brazil, Puerto Rico, Turkey, and Greece.
