The city overtook Boston to become the country's second-largest tech center, after Silicon Valley, reported CNNMoney in December 2012.

A report by The Center for an Urban Future in May 2012, found that thousands of tech jobs have been added in New York City over the past few years when other industries have been hurting amid a struggling economy. Over the past five years, tech-related jobs in the Big Apple have increased by 28.7 percent from 41,100 to 52,900.

The news comes as more tech companies open offices in New York. Just last week, both eBay and Microsoft announced they will be expanding in New York City. eBay said the new location will house more than 200 people in the next few years.

Meanwhile, Facebook announced in December that it would open a New York engineering office and Google purchased a 2.9-million-square-foot building in Manhattan’s Chelsea neighborhood in December 2010 for a reported $1.9 billion.
