Twitter promotes advertising products to 50 countries and regions during the year

Twitter, which earned about $139.5 million last year and found a business model for the mobile market, is now the biggest hurdle for promoted products, which are being launched only for the US, UK, Japan and Canada. But that will soon change, according to Bain.

A Twitter spokeswoman later said the company would focus on expanding into the European market, with countries such as Spain, Italy, Germany, France and the Netherlands promoted in the second half. Latin America and the Caribbean will also be the target of recent expansion.

A massive international expansion is important for Twitter. According to emarketer, a market research firm, the company currently earns 90% of its revenue from the United States, while other countries and regions have only 26 million dollars in advertising revenue this year. The company's 2012 advertising revenue is expected to grow by 86.3% to $259.9 million trillion. (Ding Macro)
