It's been this way for atleast a decade, possibly 2.
As a matter of fact, that type of plug was standardised in the early 1960s. It has been around literally for generations.
This »Europlug« design is popular for devices requiring up to 2.5 A which do not need to be grounded, in all European countries except the UK, Ireland, and a few other places that use the UK system like Malta or Cyprus. The Swiss system is also subtly different. There are other, more sturdy plugs used for equipment that requires stronger currents, must be earthed, or is used outside.
The UK system uses large plugs with three rectangular prongs. These plugs are usually fused, and are incompatible with the Europlug, although UK bathrooms will often feature Europlug sockets to accommodate electric shavers. It is possible to manufacture »converter« plugs that fit around a Europlug, contain the requisite fuse, and have the three prongs required for a UK socket.
