Austin, TX long ago passed a law that said a billboard can be used to advertise only for the business on the parcel of land where the billboard is physically located. Thus, a car repair shop could have a billboard advertising themselves, but they are not allowed to lease it out to advertise, say, a tanning salon that is not on the same site. At the time it was passed, any existing billboards were granted an exemption, and can be leased to show arbitrary ads. There has been a trend to replace those billboards with digital versions. Austin passed a law to prevent such conversions, but it has been challenged up to the Supreme Court, as the advertising companies which own all those "analog" billboards claim their first amendment rights have been violated. https://www.kut.org/austin/2021-11-09/austins-billboards-supreme-court-first-amendment-speech-content https://www.kut.org/austin/2021-11-09/austins-billboards-sup...
