             (Date of Events Which Require Filing of This Statement)

If the filing person has previously filed a statement on Schedule 13G to report

==============================================================================







      This Amendment No. 9 amends the Schedule 13D originally filed on March 19,
1999 (as amended by Amendment No. 1 filed on March 30, 2000, Amendment No. 2
filed on September 5, 2000, Amendment No. 3 filed on January 12, 2001, Amendment
No. 4 filed on April 19, 2001, Amendment No. 5 filed on May 22, 2001, Amendment
No. 6 filed on June 12, 2001, Amendment No. 7 filed on October 1, 2001, and
Amendment No. 8 filed on October 4, 2001, the "Schedule 13D") by AT&T Corp.
("AT&T") and relates to shares of Series A common stock, par value $0.01 per
share (the "Series A Common Stock"), of At Home Corporation, a Delaware
corporation ("Excite@Home" or the "Issuer"). The Issuer's principal executive
offices are located at 425 Broadway Street, Redwood City, CA 94063. Pursuant to
Rule 13d-3 under the Exchange Act, this Amendment No. 9 also relates to the
shares of Series A Common Stock issuable upon conversion of shares of the Series
B common stock, par value $0.01 per share ("Series B Common Stock"), of
Excite@Home. Capitalized terms used without definition in this Amendment No. 9
shall have the respective meanings ascribed to them in the Schedule 13D.
References to "herein" and "hereof" are references to the Schedule 13D, as
amended by this Amendment No. 9.

ITEM 4.  PURPOSE OF TRANSACTION.

      Item 4 of the Schedule 13D is hereby amended by adding the following at
the end thereof:

      On October 23, 2001, by written consent delivered to Excite@Home in
accordance with the terms of the @Home Charter, AT&T removed, effective October
1, 2001, C. Michael Armstrong, Frank Ianna, Charles H. Noski and Daniel E.
Somers as Series B Directors.

      At the same time, AT&T delivered a letter to Excite@Home in which AT&T
irrevocably relinquished, effective October 1, 2001, its rights to appoint any
replacement directors for the Series B Directors that were removed by the
written consent, and further agreed not to seek to appoint or designate
additional directors such that after any such appointment or designation
directors appointed or designated by AT&T would constitute a majority of the
Excite@Home Board of Directors. As a result, beginning in the fourth quarter of
2001, Excite@Home will be treated by AT&T as an equity investment for accounting
purposes, and Excite@Home's results and financial position will no longer be
included in AT&T's consolidated financial reporting.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
RESPECT TO SECURITIES OF THE ISSUER.

         The third paragraph of the response to Item 4 is repeated and
incorporated herein by reference.
