1962 Ultra Radio and Television Ltd. introduced a new range of receivers called the "Smart Set". The range comprised three 19" TV, two radiograms, four transistor sets (one a VHF table model) and a mains operated record reproducer. The company's Bermuda trade mark was retained; all sets were fully convertible to 625 lines.
1974 Thorn dropped the Ultra brand name as the consolidated (but brand name-heavy) industry fought against the very strong Japanese imports.
