Using the festivities of Internet Week New York to tout the city's tech sector gains, Mayor Michael Bloomberg unveiled an interactive map of industry jobs on Tuesday at the Mercer Street headquarters of the annual event. The Made in New York Digital Map draws together some 600 industry-related companies, including startups, investors and co-working spaces and incubators. The map offers links to job listings on the companies' web sites and will be continuously updated. More than 320 companies said they had about 1,000 job openings. “We expect this map to be another tool that helps propel our tech industry forward,” Mr. Bloomberg said. The mayor described the site as an invitation to engineers and developers across the country and around the world to come to New York. “The map reflects the phenomenal development that is happening here,” added Rachel Sterne, the city's chief digital officer . The Made in New York map is the latest effort by the Bloomberg administration to hype technology growth in the city, which had lagged behind Boston and Silicon Valley as a tech center. According to a report released last week by the Center for an Urban Future, however, New York was the only leading technology region to post an increase in the number of venture capital deals between 2007 and 2011, and now trails only Silicon Valley as a hub for tech-related deal making. In terms of the total dollar-value of venture capital investments, however, New York still has some catching up to do. Though it surpassed New England for one quarter last year, the city finished in third place overall in 2011 and trailed not only Boston but Texas and Los Angeles in the first quarter of 2012, according to the MoneyTree Report from PricewaterhouseCoopers and the National Venture Capital Association, based on data from Thomson Reuters. The map was created by Internet Week New York in partnership with the Mayor's Office of Media and Entertainment and the New York City Economic Development Corp.
