Yes, but that's obvious, at least to people in the biz.
I read somewhere that more composers are writing music for video games than are working on movies. That was seven or eight years ago.
There was a movie entered at Sundance a few years ago that was made entirely using an iPhone with an "anamorphic" lens attachment (the movie was Tangerine, and the lens is made by Moondog Labs of Rochester, NY).
These factors are part of larger trends that will over time erode Hollywood's position.
Did you know that a complete sound studio mix board can now be held in the palm of your hand? In fact, there are sound mix apps for the iPhone, as well as various types of synthesizers, some of which take input from one instrument and convert it to the sound of another instrument. Of course, software for creating and editing video and sound is readily available and very inexpensive.
See post 32 and 39. The independent movie makers are going to be the rue of Hollywood.
Tangerine available on Netflix. I will have to check it out.
