MTV - Magyar Televízió

MTV trademark suit
Magyar Televízió, who has a trademark on the initials MTV registered with the Hungarian copyright office, sued the American MTV Music Television network for trademark infringement when MTV Music Television launched a Hungarian-language channel in 2007. The suit is still ongoing.

Location
The Hungarian Television's central building was located in the heart of Budapest on Szabadság tér (Freedom Square), across the Hungarian National Bank (Magyar Nemzeti Bank), the U.S. Embassy, and near to the Parliament. The building gave room to the Stock Exchange before the war. It is sold now and MTV has moved to the outskirts of Budapest to a purpose-built modern building.
