As early as 1906, various film entrepreneurs began to discuss the potential of home viewing of films, and in 1912, both Edison and Pathé started selling film projectors for home use. Because making release prints was (and still is) very expensive early home projector owners rented films by mail from the projector manufacturer. Edison's business model was fundamentally flawed because the company had started with phonographs and did not understand that home viewing is fundamentally different from home listening. Edison ended its home viewing business in 1914, while Pathé remained somewhat longer, but exited at some point during World War.
