Why might some critics view the introduction of sound as having a negative impact on the film business?

Film production or business is one of the few nationally subsidized media businesses in the United states. Understanding the importance of quality sounds in movies, games and songs is a crucial part of understanding what it means to be a successful and memorable. However, some critics view the introduction of sound as having negative impact on the film business because smaller filmmakers were forced to close and therefore increasing the hold of big studios on the industry.

Lol yes , why are you asking ?
