Corporate America is joining the access economy. You can already see signs of this trend with companies like Hertz, BMW, Ford and GM partnering with collaborative consumption companies, or even start a sharing service of their own. BMW, as we learned at SXSW has partnered ParkAtMyHouse.com, Ford partners with Zipcar, Hertz started its own car sharing service – Hertz on Demand, and GM has invested in RelayRides. It’s interesting to see the growing level of interest of large corporations in the sharing space, which sometimes seems to be at odds with the economic model their sales are based on. Take for example the case of GM.
