The British Darts Organisation (BDO) was founded on 7 January 1973 by Olly Croft and was also a founder member of the World Darts Federation (WDF) which was formed in 1976. Initially, the BDO managed the England events, the England squad, as well as national events, included the World Masters, and the World Professional Championship. But following the withdrawal tobacco sponsorship in 2007, the BDO withdrew its support for England.
In 2007 England formed their own organisation' England Darts Organisation' (EDO) and joined the WDF in its own right.
In 2019 following a WDF ruling stated that the BDO didn't represent a home nation; England, Scotland, Wales or Northern Ireland as they were all members of the WDF in their own right. The BDO membership was reduced associate member.
The BDO made additional changes in 2019 changing dartboard sponsorship and moved the iconic World Championship from the Lakeside venue to the O2 arena.
The 2020 World Championship was marred by the lack of sponsorship with the move, usually supported by Bob Potter's Lakeside complex. The result, the BDO vastly reduced the player's prize money. The full extent of the reduction, however, wasn't know until the championships had finished.
Many of the top BDO players including the women dart players flocked to the PDC Q-School with expectations of winning a two year two card. The well structured PDC has a lucrative system with over £14M in prize money (2020). Several players were successful, including Lisa Ashton who became the first lady to win a tour card.
The BDO was instrumental in organising the British Country Championship (BICC). However, a lack of faith in the management lead to more than one challenge to take over the running of the events. In an open vote, the newly established United Kingdom Dart Association (UKDA) came out the majority winner to manage the events from 2020 – 2021 season.
According to Wikipedia, the BDO went into liquidation September 2020.
