Screenvision, a joint venture between ITV and Thomson, a provider of technology services and equipment to the media and entertainment industries, has more than 15,000 cinema screens across the US.
ITV has been looking to sell the business for over a year, as it continues to offload its non-core assets to reduce mounting debt.In the past two years, ITV has sold its stake, Liverpool FC's website and Carlton Screen Advertising, the UK's largest cinema advertising sales house.
The completion of the deal will be subject to anti-trust clearance.
Adam Crozier, ITV chief executive, said: "This is another important step for ITV as we progress our transformation plan to focus the business on its core objectives of UK multi-platform broadcasting and global content. The proceeds of this sale will positively impact our net debt, which decreased by £175m in the six months to 30 June 2010."
