Boston-based Backchannelmedia said this week that it’s moving from an extended period of beta testing to launching commercial operations in the New York area. The company, whose motto is “TV and the Internet finally just click,” has created a system that allows TV viewers to click using their remote controls in response to special onscreen offers and Web addresses, bringing additional information to their e-mail inboxes. Backchannelmedia says it hopes the “Clickable TV” technology will become a mainstream tool for targeted interactive marketing. The company was founded in 2000, has 29 employees, has raised $15 million in funding, and is expecting a full launch by mid-2010 with more funding.
