Seeburg was one of the first manufacturers to have a multi-select jukebox. In 1949 it developed a mechanism that could play both sides of the record and it was so reliable that few other manufacturers could compete. Seeburg introduced the M100B in 1950 – it was the first jukebox that could play 45rpm records and this was followed by the V200, the first 200-select jukebox. They continued manufacturing jukeboxes throughout the 1970's and 1980's until they were bought by Seeburg Satellite Broadcasting.
