The names are all for the same product. No idea why - marketing/PR I expect. :)
As far as I'm concerned it's easier to say Froogle than the others when describing the service to people. Who could guess what Base was? And since they couldn't go back to Froogle (never go back!) they had to go to something else, I suppose.
In an email to me concerning a recent problem (see my recent posting here), google states the service is till in Beta so to expect inconsistencies and bugs (such as not sending out emails when your shop dies). Not bad for 5 years work. :(
