Global business-to-consumer e-commerce sales will pass the 1 trillion euro ($1.25 trillion) mark by 2013, and the total number of Internet users will increase to approximately 3.5 billion from around 2.2 billion at the end of 2011, according to a new report by the Interactive Media in Retail Group (IMRG), a U.K. online retail trade organization.
The study estimates that business-to-consumer e-commerce sales in 2011 increased to 690 billion euros ($961 billion), an increase of close to 20% from a year earlier .
The United States remains the world’s single biggest e-commerce market, IMRG says, followed by the United Kingdom and Japan. IMRG estimates that growth rates in those countries will be approximately 10-15% a year. But with China’s e-commerce sales growing more than 130% in 2011, it is only a matter of time before the Asian giant becomes the single largest market in the world. source
