TV-Answer - TV-Answer was a mid 80s to early 90s two-way cable/satellite TV developer based in Reston, Virginia. TV Answer spent dozens of millions of dollars in developing its two-way cable TV system. This system allowed home viewers to communicate with their TVs via a remote control which activated a set-top box near the TV that then sent the response via radio link to TV Answer's central control system.
