The SCART connector was developed by the French, originally for the sole purpose of preventing foreign TV imports, previously the French had legislation that prevented any TV imports unless the set was capable of receiving the old French 819 line monochrome system. This effectively stopped any foreign sets from being imported, but the demise of the 819 line system prevented this from being a valid reason for banning imports, so in order to try and maintain their private market they introduced the SCART socket, and passed legislation that said all TV's sold in France since 1980 must have a SCART socket. This was obviously much less of a deterrent, it was far simpler for TV manufacturers to add a SCART socket than to produce a dual-standard set, and the SCART was actually useful elsewhere with the development of cheap home video recorders.
