There are a couple of old manifestos from the early 1990s that could be worth reading. Links are here:

Market share is easy. OODBs are a few % of RDB/ORDB. I've been involved with the technology for over 10 years (as a researcher, consultant, publisher) and it has never grown beyond a few %. My interest is applied-research, so I like looking at some of the business issues associated with technology adoption. You might find some of my slides/presentations useful:

These days (during the course of my work, networking at conferences, etc.), I rarely find anyone interested in using OODBs. Many of the vendors have also re-positioned their offerings (e.g. XML, J2EE caching). It is also hard to find any analysts (e.g. Gartner) that bother to track the OODB market anymore.
