Sony, Panasonic, and other popular projector companies all focus on electronics. They make televisions, stereos, and other consumer electronics as well as projectors. In fact, you can probably bet that many of the typical electronics manufacturers only got involved in manufacturing projectors because consumer demand was increasing in terms of home theater needs and other projector uses. This isn't to say that these companies don't create great products, but just that they aren't committed to only producing projectors and therefore a company that is focused only on projection might have better products because their resources are not spread out across the electronics industry.
