The term ‘billion’ is used more and more today. A lot more people are becoming billionaires, the bonuses of top executives are often expressed in billions, profits of large companies or corporations and the gross domestic products (GDP) of most countries are usually expressed in billions of dollars; stars and galaxies are numbered in billions, or billions of billions, as are the number of neurons in the human brain.
