The Radio Act of 1927 was enacted so as to pre-empt the common law pro
perty rights then being asserted over radio waves, thus facilitating a
political equilibrium where broadcasters and regulators shared licens
e rents. The Oak Leaves case of November 1926, awarding AM frequency r
ights to a private broadcaster on the homesteading principle, helped m
otivate Congress, steering it towards a ''public interest'' licensing
law. The Twight paper, while ostensibly critiquing this now standard v
iew in the law and economics literature, actually endorses it. The exi
sting history stands corroborated, uncorrected.
