It's about Revit Market, a newly started marketplace for quality Revit content, mainly for architects at this time. Hence the full name Revit Architecture Market. There are about 200 Revit families available for (chargeable) download today. I guess we'll see if this turns into a success, like Ms. Bousquet predicts. I will certainly be keeping an eye on this site.
The company behind this is Turbosquid, well known for their 3D-content for visualization.
