To me, Dassault Systemes always seemed to be this massive French company that owns a bunch of technology companies, but always just sat back and let these companies run as separate entities. Always known as having CATIA as the heart of their PLM inititative. They began a campaign of acquiring technologies about 10 years ago. Here is a quick list of the highlights.
SolidWorks (1997)
SRAC (2001)
ABAQUS (2005)
Matrix One (2006)
ICEM Surf (2007)
Engineous (2008)

DS has always done a great job acquiring some of the most successful companies. What they have also done well is just leave these companies to operate as a bunch of small profitable, successful entities. The CATIA/SolidWorks combination is a great example of two extremes that serve different markets and were allowed to continue doing what they do.

But things seem to be changing recently. DS has recently re-branded ABAQUS to Simulia. But a bolder move is the buzz that SolidWorks is now, Dassault Systemes SolidWorks Corporation. The Cosmos line is now SolidWorks Simulation. May seem like simple name changing, but I think it falls in line with the industry, in general.
Only a few years ago, there were numerous companies in the MCAD and FEA space, these numbers are dwindling due to acquisitions etc. In the not so distant future, there will only be a "few" monster companies that are able to offer us (the consumer) "everything". Sounds relatively familiar.
Circa, 1995, the MCAD world seemed pretty set in stone in the pre "PLM" days. You had PTC, UGS, SDRC and DS battling it out in the 3D space. Autodesk was the master of its own domain in the 2D world. In the FEA market there was MSC, HKS and ANSYS along with some of the other players like SRAC and SDRC. But for the most part, this was the playing field. Then SolidWorks and others blasting into the market and simply changed the way we look at things. This was in the days when a 3D MCAD investment was on the order of ~$40k ($20k for software and $20k for a computer to run it).
Point of my rant here is that I love the fact that these massive companies are becoming powerhouses in their own right. No doubt there will be some serious technology leaps that are made. No doubt a serious challenge for them is to manage all of the technology and not forget their biggest asset, us, the users. Look at our friends Microsoft. More importantly, I am excited to see what disruptive technology will come along to again change the market upside down.
