John Marshall Harlan II,
United States v. Southwestern Cable Company…
“ Nor can we doubt that CATV systems are engaged in interstate communication, even where, as here, the intercepted signals emanate from stations located within the same State in which the CATV system operates. [29] We may take notice that television broadcasting consists in very large part of programming devised for, and distributed to, national audiences; respondents thus are ordinarily employed in the simultaneous retransmission of communications that have very often originated in other States. The stream of communication is essentially uninterrupted and properly indivisible. ”
