Paul Allen's giant plane takes shape in the desert, but its market is unclear (seattletimes.com)

For those interested in learning about the many parties involved in the launch market this gives a pretty good general overview. I thought this article did a good job of going over not only Paul Allen's foray, but also the other well known (SpaceX, Blue Origin, ULA) and lesser known (Rocket Lab) start ups. It also speaks a little about how the satellite market has changed in 5 years as well.

As an aside I find it interesting that there is a definite trend of men who have made their wealth in through computer science competing now in this area.
