South Korea was first to market with a 3DTV, but on May 19th the country will begin the world's first terrestrial broadcasts in 3D.
The Korea Communications Commission made the announcement that all four of the channels, KBS, MBC, SBS and EBS will start trialing it in a little over a week, with the first thing to broadcast in 3D being the 2010 Colorful Daegu Pre-Championships Meeting, on the KBS channel. Following that, SBS will show the FIFA World Cup in June, with 25 of the matches being shown in 3D. [Korea Times via Akihabara News]
