[2] He gained popularity for his elaborate productions of film during the silent era, most notable for his musical accompaniments that included: overtures, prologues, interludes, and countless other vocal and dance numbers.

Here, he first identified the importance of musical accompaniment, and spent the rest of his tenure as manager improving the sonic qualities of film exhibition.

Giving the orchestra members a say in exhibition helped enhance the relationship between audio and visual elements in cinema at the time.

He was well known for introducing numerous musical and stage novelties, such as prologues, overtures, light shows, dance numbers, and radio broadcasts.

He was very successful at securing popular musicians and dancers to perform at his theatre, namely: Charles Wakefield Cadman, Victor Herbert, Van and Schenck, Ben Bernie, Vincent Lopez, The Happiness Boys, and The Goodrich Silvertown Orchestra.

Overtures originated in European operas, but Hyman and other exhibitors adopted this practice to set the mood of their motion picture for their audience.

During his time with this motion picture chain, Hyman was active in film acquisition, securing performers, and in implementing up-to-date musical and cinematic innovations.

After he resigned from his position with the now defunct Stanley Corporation, Hyman briefly continued to write publications for trade journals.

The company experienced great economic success after the merger, and was purchased by Capital Cities in 1985 for $3.5 billion in a monumental deal financed by Warren Buffett.
