Venture capitalists are placing their bets on using commercial drones on U.S. airspace, according to a report by Bloomberg. 

Tim Draper,a venture capitalist, would be investing in DroneDeploy, a startup that creates software for unmanned aircraft that does land mapping and surveillance of farm fields. Draper believed drones would allow companies to deliver goods and services without human involvement.

"Everything from pizza delivery to personal shopping can be handled  by drones," Draper told Bloomberg via email.

The amount of venture capital invested in drones doubled since 2012, according to various data and reports. During the first nine months of 2013, US venture capitalists had invested USD40.9 million into drone-related startups. Drones were projected to be used for a wide range of purposes - from specialized military reconnaissance to different civilian activities.

"Sales of civilian unmanned aerial vehicles, or UAVs, will reach USD8.2 billion within the decade, up from nothing today. There will be a lot of growth in this market." Phil Finnegan, director of corporate analysis at Teal Group that tracks aerospace and defense, told Bloomberg.
