While the 2008 Olympics were the first to be
broadcast entirely in HD, the 2012 Olympics are the first to
broadcast in HD as well as 3D. The games were first televised in
Berlin in 1936 and played on big screens about the city. Then came
the first games to enter households, strictly in London in 1948,
followed by the first internationally televised games during the
1960 Olympics in Rome.
