ITEM 1. SECURITY AND ISSUES

                 This Amendment No. 8 to statement on Schedule 13D (this "Statement") relates to the Common Stock, par value $.10 per share (the "Common Stock"), of Acxiom Corporation, a Delaware corporation (the "Issuer" or the "Company"), the principal executive offices of which are located at P.O. Box 8180, 1 Information Way, Little Rock, Arkansas 72203.

                 This Amendment No. 8 amends and restates in full each of the items set forth below. Capitalized terms used but otherwise not defined herein have the meanings ascribed to them in the Schedule 13D originally filed November 29, 2006 (the "Original Statement").

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

                 The total purchase price of the 151,500 shares of Common Stock (the “Shares”) purchased by MMI Investments was $3,493,701; the source of funds is a combination of MMI's working capital and margin loans. These margin loans were obtained from Bear, Stearns & Co. Inc. and Merrill Lynch & Co. under customary terms and conditions. The entire principal amount of such margin loans remains outstanding as of the date of this Statement.

ITEM 4. PURPOSE OF TRANSACTION

                 MMI Investments purchased the Shares as part of its investment activities. The Reporting Persons intend to review and evaluate the investment by MMI Investments in the Common Stock of the Issuer on an ongoing basis and may, depending upon their evaluation of the business and prospects of the Issuer, or such other considerations as they may deem relevant, determine to increase (but not more than 14.9% of the outstanding Common Stock), decrease, or dispose of MMI Investments’ holdings of Common Stock. As a part of such review and evaluation, the Reporting Persons may communicate with the Issuer’s management, directors and other shareholders, including as described below.

                 On May 16, 2007, the Issuer announced that it had entered into a definitive merger agreement (the "Merger Agreement") to be acquired by Silver Lake and ValueAct Capital (the "Proposed Merger"). According to the Issuer’s press release, under the terms of the Merger Agreement, shareholders of the Issuer would receive $27.10 per share in cash at the closing of the Proposed Merger. On May 18, 2007, MMI Investments submitted to the Issuer’s Board of Directors a letter, filed as Exhibit 2, hereto, expressing its then-current intention to vote its shares in opposition to the Proposed Merger and outlining its reasons for such intention. The foregoing description of the letter is qualified in its entirety by reference to the copy of the letter attached hereto as Exhibit 2 and incorporated herein by reference.

                 On May 29, 2007, MMI Investments transmitted to the Issuer a Notice, as required by Article II, Section 15 of the Issuer's By-Laws, that MMI Investments proposes to nominate for election as directors at the Issuer's 2007 Annual Meeting of Stockholders for a term ending in 2010, John S. Dyson, Clay B. Lifflander and Alan L. Rivera. The position, principal occupation and business address of each of Messrs. Dyson and Lifflander are shown on Schedule I. Mr. Rivera is a Member, Executive Vice President and Secretary of MCM, and a Voting Member, Executive Vice President Chief Financial Officer and General Counsel of Millcap Advisors, LLC. Mr. Rivera's business address is 1370 Avenue of the Americas, New York, NY 10019.

                 As a result of some or all of the actions described in the preceding paragraph, MMI Investments may no longer be able to rely on the exemption under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") for shares held solely for investment purposes and, accordingly, in order to retain its flexibility to determine, as described above, to increase (but not to more than 14.9% of the outstanding Common Stock of the Issuer) MMI Investments' holdings of Common Stock where the value of such holdings upon any such increase exceeds $59.8 million. MMI Investments on June 11, 2007, filed a Notification and Report Form under the HSR Act, seeking clearance for such acquisitions. MMI Investments was granted early termination of the waiting period pursuant to the HSR Act on June 28, 2007.


- Page 5 of 11 -


                 On July 13, 2007, MMI Investments submitted to the Issuer’s Board of Directors the letter filed as Exhibit 3 hereto regarding MMI's opposition to the Proposed Merger and the reasons therefor and expressing its then-current intention to file proxy materials with the SEC to solicit votes against the Proposed Merger. As part of the Reporting Persons' ongoing review of the Issuer, the Reporting Persons reassessed the Proposed Merger in view of the substantial and unanticipated deterioration in conditions within the equity and debt markets. On August 14, 2007, upon consideration of such changed circumstances, MMI Investments determined not to solicit proxies in opposition to the Proposed Merger. Based on its continued review and evaluation of the Proposed Merger, on September 21, 2007 MMI Investments determined to support the Proposed Merger. However, on October 1, 2007, the Issuer announced that it had entered into a Mutual Termination Agreement and Release relating to the Merger Agreement, pursuant to which the parties thereto terminated the Merger Agreement. As a result, the Proposed Merger will not be consummated. The Reporting Persons subsequently determined to decrease their holdings of Common Stock as reflected herein and do not intend to pursue the director nominations described above at the Issuer’s 2007 Annual Meeting of Shareholders.

                 Other than as described in this Item 4, neither Reporting Person, nor, to the knowledge of each Reporting Person, any individuals listed on Schedule I, has any current plan or proposal that relates to or would result in any of the transactions or other matters specified in clauses (a) through (j) of Item 4 of Schedule 13D; provided that the Reporting Persons reserve the right to develop such plans or proposals. Depending on various factors, including, without limitation, the Issuer's financial position and business strategy, the price levels of the shares of Common Stock, and conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, purchasing additional shares of Common Stock, selling or otherwise disposing of some or all of their shares of Common Stock, or changing their intention with respect to any and all matters referred to in this Item 4.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

    (a)-(b)    Based on 80,635,643 shares of Common Stock outstanding as of August 6, 2007, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on August 8, 2007, the Shares owned by MMI Investments represent approximately 0.2% of the outstanding Common Stock. MMI Investments has the sole power to direct the vote and disposition of such Shares on the date of this Statement. However, by virtue of being the general partner of MMI Investments, MCM may be deemed to be the beneficial owner of the Shares owned by MMI Investments and to have sole power over the voting and disposition of such Shares as a result of its having the sole power to make voting and disposition decisions on behalf of MMI Investments with respect to such Shares.

                Except for the Shares owned by MMI Investments, as of the date hereof, neither MCM nor, to MMI Investments' and MCM's knowledge, any of the persons listed on Schedule I, owns any Common Stock of the Issuer or has any right to acquire, directly or indirectly, any beneficial ownership of other Common Stock of the Issuer.

    (c)        Except for the open market sales of Common Stock by MMI Investments set forth in Schedule II attached hereto and incorporated herein by reference, there have been no transactions with respect to the Common Stock during the past 60 days or since the most recent filing on Schedule 13D (whichever is less) by MMI Investments, MCM, or, to either Reporting Person's knowledge, any of the persons listed on Schedule I.

    (d)        No person other than MMI Investments is known to either Reporting Person to have the right to receive or the power to direct the receipt of dividends from or the proceeds from the sale of, any of the Shares referred to in Item 5(a) above.

    (e)        The Reporting Persons ceased to be the beneficial owner of more than 5% of the outstanding Common Stock on October 2, 2007.
