Twitter is planning to expand its advertising products to as many as 50 countries by the end of this year.

The news comes from an article in The Guardian about Jack Dorsey’s and Dick Costolo’s comments today at a news conference in Cannes, France. Twitter itself hasn’t announced the expansion on its advertising blog yet, but The Twitter Advertising account on Twitter did retweet the Guardian’s article earlier today.

The Guardian says that Twitter is planning to launch three ad products — Promoted Tweets, Promoted Accounts and Promoted Trends — into Brazil and other Latin American countries, along with western European nations like Spain and Germany.

Those three countries already appear as options on Twitter’s English-language start advertising form.

Twitter CEO Dick Costolo said “there is a ton of demand but we don’t have dates as yet” for the advertising expansion.

Recent estimates have suggested that Twitter could reach a billion dollars in sales revenue by 2014. The company recently pushed its ad products to mobile devices and has also begun to slowly launch a self-serve ad platform for small business owners.
