Item 1. Security and Issuer
This Amendment No. 56 to Schedule 13D on the Cablevision NY Group Class A Common Stock of Cablevision Systems Corporation (the “Issuer”) is being filed on behalf of the undersigned to amend the Schedule 13D, as amended (the “Schedule 13D”) which was originally filed on December 11, 1995.   Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth the Schedule 13D.
Item 2. Identity and Background
Item 2 to Schedule 13D is amended, in pertinent part, as follows:
