Twitter has come along way since saying it could make money without advertising.
That number could double by next year as advertisers look to connect with Twitter's more than 175 million users.
Twitter told investors in 2009 that it could make money by developing add-on tools and avoid annoying users with ads.
But that plan was modified in April last year when Twitter began introducing ads on its site.
