cameras to cover the sport, and many of these innovations have been copied by other broadcasters. Unique flight cams show the trajectory of the dart through the air in slow motion to sometimes surprising results. A tiny camera has also been inserted into the dartboard itself beside the number 16 – one of the most common doubles – that shows the darts being thrown towards the board. Sky Sports have also used a player cam; a tiny camera was fitted to Dennis Priestley's shirt to capture his view of the action while playing. Elsewhere, floating video cameras capture the action of the watching crowds. Spectators become far more animated and vocal than their BDO counterparts, often acting similar to a football crowd, while holding up humorous placards – often featuring corny puns – regarding the players, and chanting or singing various songs related to the players or to the event in general. Some supporters even wear face paint or crazy costumes or they dress up as their favourite player via their trademark attire or customary nickname. The players' wives have also been a focus for the cameras, as they cheered or screeched on their husbands. In January 2005, Sky One commissioned a programme entitled Darts Players' Wives, primarily focusing on the wives and their relationships. In December 2008, Sky started to broadcast darts in High Definition (with the exception of the final Las Vegas Desert Classic in 2009), and in July 2010 (at the World Matchplay), broadcast the Semi Finals and Final in 3D to around 1,000 licensed premises in the UK and Republic of Ireland. Another frequent cam is a split-screen camera, with the players on the right, and the dartboard on the left. If the first two darts hit the triple 20, the camera will zoom in to the spot before the third dart is thrown. Commentators John Gwynne has covered all PDC events from the inaugural 1992 competition until his retirement in 2013. Dave Lanning covered all events up until December 2010, when he retired. Contrary to popular belief, long-time BBC darts commentator Sid Waddell did not switch allegiances to Sky until after the 1994 BDO World Championship. He brought his own unique brand of commentary to the game, and was a cult figure amongst darts fans and sport fans alike. He continued to commentate until his death in 2012. The current commentators on Sky include Rod
