What are you talking about? There has been almost zero venture capital invested in space tourism.
I worded that poorly. I meant venture capital in non-NASA (hence private) efforts, not necessarily aimed at tourism. There have been two (that actually got to the point of building hardware) private launch industry efforts (if memory serves me), trying to develop launch facilities and vehicles, but I believe the prospectus did mention tourism as a potential return on investment. I don't honestly know how much venture capital they were able to draw in.
