The news was first made public on the service’s website and at a conference in Las Vegas, and the company further revealed the expansion is funded by a $38 million B round:

The decidedly MacGyver tech behind Aereo relies on fingertip-sized TV antennas in data centers that allow servers to live-stream channels with high-definition reception through a speedy Internet connection. Aereo also works with Apple TV via iTunes’ AirPlay and a source iOS device, and even Roku-lovers can use the Aereo channel through set-top boxes. The service flaunts 40 hours of DVR storage space and an HTML 5 experience. That’s right, no apps—nor cords, cables, and boxes; hence the startup’s “It’s TV made simple” badge.

Aereo was an invite-only, 90-day free trial to New York City residents, but now other cities, such as Chicago, can enjoy its in-market TV experience. As AllThingsD noted, New York City residents cannot use Aereo to watch a Bears game via a Chicago station because of the in-market limitations, but the expansion will give more than 97 million American consumers the choice to access over-the-air broadcast television

No cable subscription is required to use Aereo and membership plans begin at $1 per day, $8 per month, or $80 per year. For more information, check out Aereo’s press release (PDF) or watch a replay of today’s event at Veracast.
