Recently, we wrote about a proceeding initiated by the Copyright Office to review the reporting obligations of cable and satellite television systems related to the statutory license that permits those systems to carry the programming of local television stations.  Systems must report information including revenue and subscriber information that allow royalties to be computed.  This proceeding also included a section asking for comments on the Copyright Office’s tentative conclusion that the Copyright Act’s definition of a cable system did not extend to online services, like those that had been proposed by Aereo and FilmOn.  See our article here about the Copyright Office’s request for comments.  The Copyright Office has just announced that they are extending the comment period in this proceeding.  Comments are now due March 16, with replies due on April 6, 2018.
