CUSIP No. 573083102

Item 1. Security and Issuer

This Amendment No. 1 to the statement on Schedule 13D (the “Amendment No. 1”) relates to the Class A common stock par value $0.01 per share (the “Class A Common Stock”) of Martha Stewart Living Omnimedia, Inc., a Delaware corporation (“MSLO” or the “Issuer”). The principal executive office of MSLO is located at 601 West 26th Street New York, New York 10001.

This Amendment No. 1 constitutes an exit filing for SQBG, whose beneficial ownership has dropped below the 5.0% Schedule 13D reporting threshold. This Amendment No. 1 hereby amends the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on June 22, 2015. Unless otherwise stated herein, information reported in the Schedule 13D, as amended, remains in effect except to the extent that it is expressly amended, restated or superseded with information contained in this Amendment No. 1.

Item 2. Identity and Background

This statement is being filed by SQBG, Inc. (formerly Sequential Brands Group, Inc.) (“SQBG”), a Delaware corporation and the predecessor issuer by merger to Sequential Brands Group, Inc. (formerly Singer Madeline Holdings, Inc.), a Delaware corporation (“New Sequential”). The principal executive office and business of SQBG is located at 601 West 26th Street New York, New York 10001. Information as to each of the executive officers and directors of SQBG is set forth on Schedule I.

Item 3. Source and Amount of Funds or Other Consideration

This Amendment No. 1 is being filed to report the termination of beneficial ownership of all shares of Issuer Common Stock previously beneficially owned by SQBG as a result of the consummation of the MSLO Merger.

The Voting Agreement terminated on December 2, 2015, when the MSLO stockholders approved the Mergers. The Voting Agreement was the basis for the beneficial ownership by SQBG of Issuer Common Stock.

On December 4, 2015 (the “Effective Time”), Madeline Merger Sub was merged with and into MSLO, with MSLO surviving the merger as a wholly owned subsidiary of New Sequential. As a result of the MSLO Merger, the Issuer ceased to be a publicly traded company.

Subject to the terms and conditions of the Merger Agreement, at the Effective Time, each share of MSLO’s Class A Common Stock outstanding immediately prior to the Effective Time was converted into the right to receive either $6.15 in cash or 0.6958 shares of common stock of New Sequential, or a combination thereof. Accordingly, at the Effective Time and pursuant to the MSLO Merger, SQBG disposed of all shares of Issuer Common Stock that were beneficially owned by SQBG immediately prior to the Effective Time.

The foregoing summaries of the Merger Agreement, as amended, and Voting Agreement do not purport to be complete and are qualified in their entirety by reference to the complete text of such agreements attached hereto as Exhibits 1, 2 and 3.

Item 4. Purpose of Transaction

The information contained in Item 3 above is hereby incorporated by reference. As of the Effective Time, each of the former members of the board of directors of the Issuer and each of the former officers of the Issuer resigned. As of the Effective Time and pursuant to the Merger Agreement, Yehuda Shmidman and Gary Klein were appointed to the board of directors of the Issuer. In addition, Mr. Shmidman assumed the role of Chief Executive Officer of the Issuer, and Mr. Klein assumed the role of Chief Financial Officer of the Issuer. Except as otherwise stated herein, SQBG does not have any current plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

(a) (b) Neither SQBG and, to the best of SQBG’s knowledge, none of the individuals named in Schedule I hereto, have beneficial ownership of any shares of Issuer Common Stock.

(e) Each of the Reporting Persons ceased to be a beneficial owner of 5% or more of the Issuer Common Stock on December 4, 2015.

Item 7. Material to be Filed as Exhibits
