On2 Technologies, formerly known as The Duck Corporation, was a small publicly traded company (on the American Stock Exchange), founded in New York City in 1992 and headquartered in Clifton Park, New York, that designed video codec technology. It created a series of video codecs called TrueMotion (including TrueMotion S, TrueMotion 2, TrueMotion RT 2.0, TrueMotion VP3, 4, 5, 6, 7 and 8).
In February 2010, On2 Technologies was acquired by Google for an estimated $124.6 million. On2's VP8 technology became the core of Google's WebM video file format.
