      This Amendment No. 5 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 and
Amendment No. 4 filed on April 19, 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. 5 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. 5
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. 5.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      Item 3 of the Schedule 13D is hereby amended by adding the following to
the end thereof:

      On May 18, 2001, AT&T, Cox and Cox@Home, Inc., a wholly owned subsidiary
of Cox ("Cox@Home"), entered into a share issuance agreement (the "Cox Share
Issuance Agreement") and completed the transactions contemplated by the Cox
Share Issuance Agreement. Pursuant to the Cox Share Issuance Agreement, AT&T
issued 75 million shares of AT&T common stock to Cox@Home. As a result of this
transaction, the Put granted to Cox under the Letter Agreement, which was
exercised on January 11, 2001, has been satisfied in full. AT&T will not acquire
any Series A Common Stock in this transaction. AT&T granted Cox@Home limited
registration rights with respect to the AT&T common stock issued to Cox@Home.

      Also on May 18, 2001, AT&T and Comcast PC Investments Inc., a wholly owned
subsidiary of Comcast ("Comcast PC"), entered into a share issuance agreement
(the "Comcast Share Issuance Agreement"), pursuant to which AT&T agreed to issue
shares of AT&T common stock to Comcast PC. The exact number of shares of AT&T
common stock to be issued to Comcast PC will depend on recent trading prices of
AT&T common stock and of Series A Common Stock at the time of closing, but it is
expected to be in excess of 80 million shares of AT&T common stock. It is
expected that the transactions contemplated by the Comcast Share Issuance
Agreement will be completed in June 2001, at which time the Put granted to
Comcast under the Letter Agreement, which was exercised on January 11, 2001,
will be fully satisfied. AT&T will not acquire any Series A Common Stock in this
transaction. AT&T will grant Comcast PC limited registration rights with respect
to the AT&T common stock to be issued to Comcast PC at the closing.
