The speculation game over Twitter’s revenue is going wild. Some believe the company will bring in $226 million in revenue this year, others predict closer to $400 million, and some even think it will reach a billion in just two years.

And while it’s still private, we probably won’t be hearing any official numbers from Twitter for a while – but this infographic from TheNology.com explores what we do know.

Whether Twitter’s revenue will reach $540 million in 2014 – or whether it will explode to $1 billion as two sources told Bloomberg this month – is up for debate. The infographic explores both possibilities, and it does point out that many advertisers prefer Twitter to Facebook, which may lend credence to the high predictions.

The various types of advertising solutions on Twitter are also explored in this infographic, and a few case studies including the Red Cross and Airbnb are included to highlight how big advertisers are using Promoted Tweets, Trends and Accounts creatively.
