The International Broadcast Centre stands as a temporary media hub for broadcasters during major sport events. It serves as the central nervous system where journalists from around 190 countries gather to produce content.
The inaugural IBC was created for the Tokyo 1964 Summer Olympics during the first Olympics to be telecast internationally without tapes flying overseas. These were also the first Olympic Games to have color telecasts albeit partially.
The centre included fifteen television studios operating twenty-four hours a day seven days a week. The facility contained 966 tonnes of fir wood and nearly 700 doors within its structure.
During the UEFA Euro 2016 in France the IBC in Paris hosted journalists from around 190 countries. Each channel occupied space on the thirty thousand square meter floor separated by wooden panels.
The physical space separates each channel with wooden panels on the floor. Materials like timber and temporary paneling allowed for rapid assembly before the games began.
