A Walled Garden is a slang/pop culture term used to describe closed network or services which are designed in such a manner that they "lock" a user's account information and activities into their own network, and though they may allow a user to bring data from other locations in (but this is usually not the case), the underlying commonality is that they do not allow user's to take their data out of the network or service.
