Our principal concern is the extent to which Internet retransmissions of broadcast signals can be controlled geographically. The Internet is a worldwide system with the capability of transmitting, or retransmitting, copyrighted works to hundreds of millions of viewers within seconds. If a compulsory license were created for retransmission of local broadcast signals, it is unclear how the retransmission of those signals could be limited to their local markets. iCraveTV's feeble attempts to limit the retransmission of Buffalo television stations to Canadian viewers by requiring entry into a computer of a Canadian telephone area code and requiring the user to certify that he is receiving the transmission from a computer terminal or display device located within Canada, were ineffective. In response, copyright owners brought a successful copyright infringement suit that blocked iCraveTV retransmissions in the U.S. and, effectively, shut it down altogether. Some firms are working on software and hardware that would restrict the distribution of information, which could include broadcast retransmissions, to specific Internet customers or to customers located in a specific geographic area. But no one has yet rolled out a fail-proof system, and if experience has taught anything with technological controls to copying, it is that it is not long before they are hacked or circumvented.
