This Amendment No. 10 (this “Amendment”) amends and supplements the Statement on Schedule 13D (the “Schedule 13D”) which was jointly filed on September 17, 2008, the amended Statement on Schedule 13D which was jointly filed on December 13, 2010, the second amended Statement on Schedule 13D which was jointly filed on December 27, 2012, the third amended Statement on Schedule 13D which was jointly filed on March 14, 2013, the fourth amended Statement on Schedule 13D which was jointly filed on June 5, 2013, the fifth amended Statement on Schedule 13D which was jointly filed on May 27, 2014, the sixth amended Statement on Schedule 13D which was jointly filed on August 4, 2014, the seventh amended Statement on Schedule 13D which was jointly filed on March 2, 2015, the eighth amended Statement on Schedule 13D which was jointly filed on March 1, 2016, and the ninth amended Statement on Schedule 13D which was jointly filed on June 28, 2016, and is filed on behalf of Advance/Newhouse Programming Partnership, a New York general partnership (“Advance/Newhouse”), Newhouse Broadcasting Corporation, a New York corporation (“NBCo”), Advance Publications, Inc., a New York corporation (“API”), Newhouse Family Holdings, L.P., a Delaware limited partnership (“NFH”), and Advance Long-Term Management Trust, a New Jersey trust (“Advance Long-Term Trust” and, together with Advance/Newhouse, NBCo, API, and NFH, the “Reporting Persons” and each a “Reporting Person”), with respect to the Series A Common Stock, par value $0.01 per share (the “Series A Common Stock”), and the Series C Common Stock, par value $0.01 per share (the “Series C Common Stock”), of Discovery Communications, Inc., a Delaware corporation (the “Issuer”). The Reporting Persons directly or indirectly hold (1) shares of Series A Convertible Participating Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”), of the Issuer, which are convertible into the shares of Series A Common Stock and shares of Series C Common Stock for which beneficial ownership is reported herein, and (2) shares of Series C Convertible Participating Preferred Stock, par value $0.01 per share (the “Series C Preferred Stock”), of the Issuer, which are convertible into the shares of Series C Common Stock for which beneficial ownership is reported herein. The Reporting Persons have entered into a joint filing agreement, a copy of which is attached hereto as Exhibit A.

This Amendment is being filed for purposes of disclosing the agreement between Advance/Newhouse and the Issuer pursuant to which Advance/Newhouse has agreed to exchange its shares of Series A Preferred Stock and shares of Series C Preferred Stock (the Series A Preferred Stock and Series C Preferred Stock, together, the “Old Preferred Stock”) for 7,852,582 plus (4/9th) shares of a newly designated Series A-1 Convertible Participating Preferred Stock of the Issuer, par value $0.01 per share (“Series A-1 Preferred Stock”), and 6,218,592.5 shares of a newly designated Series C-1 Convertible Participating Preferred Stock of the Issuer, par value $0.01 per share (“Series C-1 Preferred Stock,” and together with the Series A-1 Preferred Stock, the “New Preferred Stock”), as described under Item 4 below.

Item 4. Purpose of Transaction.

Exchange Agreement

On July 30, 2017, Advance/Newhouse entered into a Preferred Share Exchange Agreement (the “Exchange Agreement”) with the Issuer, which is attached hereto as Exhibit B and incorporated herein by reference. Pursuant to the terms of the Exchange Agreement, the Issuer will issue 7,852,582 plus (4/9th) shares of Series A-1 Preferred Stock and 6,218,592.5 shares of Series C-1 Preferred Stock to Advance/Newhouse, in exchange for 70,673,242 shares of Series A Preferred Stock and 24,874,370 shares of Series C Preferred Stock held by Advance/Newhouse as of the date of this Schedule 13D. Immediately following the Exchange, Advance/Newhouse’s beneficial ownership of the aggregate number of shares of Series A Common Stock and Series C Common Stock into which the New Preferred Stock received by Advance/Newhouse in the Exchange are convertible will remain unchanged. The shares of Old Preferred Stock transferred by Advance/Newhouse in the Exchange will represent all of the shares of Old Preferred Stock issued and outstanding immediately prior to the Exchange Closing.

The purpose of the Exchange is to facilitate Advance/Newhouse’s ability to transfer or sell the shares of Series C Common Stock that prior to the Exchange Agreement were only issuable to Advance/Newhouse upon conversion of the Series A Preferred Stock.

The Exchange Closing is not subject to any closing conditions and will occur within seven business days after the execution of the Exchange Agreement or as promptly as practicable thereafter. Effective at the Exchange Closing, all outstanding shares of the Series A Preferred Stock and Series C Preferred Stock will be retired by the Issuer.

Certain of the shares of Series C-1 Preferred Stock received by Advance/Newhouse in the Exchange (including the Series C Common Stock into which such shares are convertible) will be subject to transfer restrictions, on the terms set forth in the Exchange Agreement. While subject to transfer restrictions, such shares may be pledged in certain bona fide financing transactions, but may not be pledged in connection with hedging or similar transactions.

The foregoing summary of the Exchange Agreement is qualified in its entirety by the full text of the Exchange Agreement, which is attached hereto as Exhibit B and is incorporated by reference herein.

Voting Agreement

On July 30, 2017, in connection with the Agreement and Plan of Merger (the “Merger Agreement”), dated July 30, 2017, among the Issuer, Scripps Networks Interactive, Inc., an Ohio corporation (“Scripps”), and Skylight Merger Sub, Inc., an Ohio corporation and a wholly owned subsidiary of the Issuer, Advance/Newhouse entered into a voting agreement with the Issuer and Scripps (the “Voting Agreement”), which is attached hereto as Exhibit C and incorporated herein by reference. Unless terminated in accordance with its terms, the Voting Agreement requires that Advance/Newhouse vote its shares of Series A-1 Preferred Stock to be issued in connection with the Exchange to approve the issuance of shares of Series C Common Stock in connection with the merger transactions as contemplated by the Merger Agreement.

The foregoing summary of the Voting Agreement is qualified in its entirety by the full text of the Voting Agreement, which is attached hereto as Exhibit C and is incorporated by reference herein.
