Commerce means trade, commerce, transportation, transmission, or communication among the several States, or between any State and any place outside thereof.
As amended by section 3(a) of the Fair Labor Standards Amendments of 1949.
As has been noted in § 776.7 , the word "State" in this definition refers not only to any of the fifty States but also to the District of Columbia and to any Territory or possession of the United States.
The inclusion of the term "commerce" in the definition of the same term as used in the Act implies that no special or limited meaning is intended; rather, that the scope of the term for purposes of the Act is at least as broad as it would be under concepts of "commerce" established without reference to this definition.
