Greenwood Racing and its various subsidiary companies is one of the major operators of parimutuel thoroughbred, harness and greyhound betting in North America.

In 1991, the 2DB team established the first US-based full content and fully-controllable information display system to supplement betting in both racetracks and off-track betting parlours (OTBs).

Since then 2DB have supplied numerous additional systems to Greenwood, including automated TV captioning software for their satellite TV channels, a highly successful internet betting system and specialist products that produce live data feeds of American wagering data and which distribute these to clients throughout the USA and around the world under the TRNI and Racing Channel brand names.
