Item 1.  Security and Issuer
         -------------------

     This Statement on Schedule 13D (this "Statement") relates to shares of
Ticketmaster Online CitySearch ("TMCS") Class B common stock, par value $0.01
per share (the "Class B Common Stock").

Item 2.  Identity and Background
         -----------------------

     This Statement is being filed by Microsoft Corporation, a Washington
corporation ("Microsoft").  The principal business address of Microsoft is One
Microsoft Way, Redmond, Washington 98052.  Microsoft develops, manufactures,
licenses and supports a range of software products, including scalable operating
systems, server applications, business/consumer productivity applications,
software development tools and Internet software and technologies.

     (a)-(c); (f) The name, business address, present principal occupation or
employment, and the name and principal business of any corporation or other
organization in which such employment is conducted of each of the directors and
executive officers of Microsoft is set forth in Schedule I hereto, which is
incorporated herein by reference.  With the exception of (i) Bernard P. Vergnes
and Michel Lacombe, who are a citizens of France, (ii) Joachim Kempin, who is a
citizen of Germany, and (iii) Orlando Ayala Lozano, who is a citizen of
Columbia, each person listed in Schedule I hereto is a citizen of the United
States.

     (d)-(e) During the last five years, neither Microsoft nor, to the knowledge
of Microsoft, any of the persons listed on Schedule I hereto (i) has been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration
         -------------------------------------------------

     Pursuant to an Agreement and Plan of Merger, dated as of July 19, 1999, a
copy of which is incorporated by reference as Exhibit 1, Microsoft received, at
closing and by virtue of the merger, 7,000,000 shares of TMCS Class B Common
Stock, par value $.01 per share.

     At the closing on September 17, 1999 of the transactions described above,
TMCS issued two warrants to Microsoft as consideration for the services provided
by Microsoft pursuant to a Distribution and Cross Promotion Agreement between
Microsoft and TMCS.  Warrant No. 1 entitles Microsoft to purchase up to
1,500,000 shares of TMCS Class B Common Stock at an exercise price of $60 per
share.  The purchase rights are exercisable at any time during the 5-year period
following closing.  The amount of shares purchasable pursuant to Warrant No. 1
will be adjusted to reflect any stock split, stock dividend, recapitalization,
or other event that would dilute Microsoft's interest in the absence of
adjustment.  The terms of Warrant No. 1 permit cashless exercise after the 18-
month anniversary of closing.  Microsoft is restricted from selling or otherwise
disposing of shares issuable pursuant to Warrant No. 1 for 180 days following
closing, but may engage in hedging transactions with respect to the warrant
shares.

     Warrant No. 2 entitles Microsoft to purchase up to 3,000,000 shares of TMCS
Class B Common Stock.  The warrant is exercisable at any time between closing
and the 5-year anniversary thereof, at an initial strike price of $30 per share.
The exercise price decreases, however, by $1/16 for each increment of $1/16 by
which the fair market value of TMCS Class B Common Stock exceeds $30.  The
exercise

                                       3


price cannot be reduced below $1/16. To illustrate, if, on the date of exercise,
TMCS Class B Common Stock is trading at $40, the strike price will be $20. If
TMCS Class B Common Stock is trading at $59 15/16 or higher, the strike price
will be $1/16. The amount of shares purchasable pursuant to Warrant No. 2 will
be adjusted in accordance with any stock split, stock dividend,
recapitalization, or other event having a diluting effect on Microsoft's
interest. The terms of Warrant No. 2 permit cashless exercise after the 18-month
anniversary of closing. Microsoft is restricted from selling or otherwise
disposing of shares issuable pursuant to Warrant No. 2 for 180 days following
closing, but may engage in hedging transactions with respect to the warrant
shares.

Item 4. Purpose of the Transaction
        --------------------------

     (a)-(j) On July 19, 1999, Microsoft Corporation, a Washington corporation
("Microsoft"), Ticketmaster Online-CitySearch, Inc, a Delaware corporation
("TMCS"), Sidewalk.com, Inc., a Nevada corporation and wholly-owned subsidiary
of Microsoft ("Sidewalk"), and Ticketmaster Acquisition, Inc., a Nevada
corporation and wholly-owned subsidiary of TMCS ("Sub") entered into an
Agreement and Plan of Merger ("Merger Agreement"), a copy of which is
incorporated by reference as Exhibit 1.

     Pursuant to the Merger Agreement, Sub was merged with and into Sidewalk and
the separate corporate existence of Sub ceased on September 17, 1999. As a
result of the Merger, TMCS owns 100% of the Sidewalk outstanding stock.  All
outstanding shares of Sidewalk common stock prior to the Merger were by virtue
of the Merger converted into and became 7,000,000 shares of TMCS Class B Common
Stock (the "Merger Consideration").

     Microsoft and TMCS also entered into a Distribution and Cross Promotion
Agreement in consideration of which TMCS issued two warrants entitling Microsoft
to acquire 4,500,000 additional shares of TMCS common stock.

     The foregoing summaries of the Merger Agreement, Warrant No. 1, and Warrant
No. 2 do not purport to be complete and are qualified in their entirety by
reference to the text of such agreements included as Exhibits 1, 2, 3,
respectively.

     Except as set forth in this statement, the Merger Agreement, Warrant No. 1,
and Warrant No. 2, neither Microsoft nor, to the best of Microsoft's knowledge,
any of the individuals named in Schedule I hereto has any plans or proposals
which relate to or which would result in or relate to any of the actions
specified in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer
         ------------------------------------

     (a)-(b) By reason of the Merger Agreement, Microsoft may be deemed to have
beneficial ownership of, and sole dispositive power with respect to, the
7,000,000 shares of TMCS Class B Common Stock granted to Microsoft in the Merger
Agreement, and the two warrants for 4,500,000 additional shares of TMCS Class B
Common Stock granted to Microsoft pursuant to the Distribution Agreement.  Based
on the number of shares of TMCS Class B Common Stock outstanding, Microsoft may
be deemed to beneficially own approximately 28.4% of the Class B Common Stock
outstanding, including the potential exercise of the two warrants totalling
4,500,000 shares of Class B Common Stock.  Both warrants provide for the
exercise of purchase rights at any time during a five-year period following the
closing of the Merger.

     Microsoft currently has the right to vote 7,000,000 shares of TMCS Class B
Common Stock, representing 19.5% of the class, and upon the exercise of the two
warrants for an additional 4,500,000

                                       4


class B shares, Microsoft would have the right to vote 11,500,000 shares,
representing 28.4% of the TMCS Class B Shares. Shares of TMCS Class B Common
Stock are voted as a group with shares of TMCS Class A Common Stock. Each share
of Class A Common Stock is entitled to ten votes per share, while each share of
Class B Common Stock is entitled to one vote per share. TMCS' most recent Form
10-K, dated as of December 31, 1999, stated that there were 49,664,907 Class A
Common Shares outstanding, and 35,932,320 Class B Common Shares outstanding.
Microsoft owns no Class A shares, and would have approximately 2.14% of the
combined vote of TMCS Class A and B Common Stock, if both warrants were
exercised.

     The amount listed on item 11 of Schedule 13D as beneficially owned is the
sum of (i) the 7,000,000 shares obtained upon close of the Merger and (ii) the
4,500,000 shares which may be obtained at any time upon exercise of the purchase
rights.

     (c) Except as described herein, neither Microsoft nor, to the best of
Microsoft's knowledge, any of the individuals named in schedule I hereto, has
effected any transaction in TMCS stock during the past 60 days.

     (d) Ownership of Class B Common Stock by Officers and Directors.  To the
best of Microsoft's knowledge, none of Microsoft's executive officers or
directors is known to have the right to receive or the power to direct the
receipt of dividends from, or the proceeds from the sale of any shares of TMCS
other than the following:

     (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         ---------------------------------------------------------------------
         to Securities of the Issuer
         ---------------------------

     Neither Microsoft or, to the best of Microsoft's knowledge, any of the
individuals named in Schedule I hereto has any contracts, arrangements,
understandings or relationships (legal or otherwise) with any person with
respect to any securities of TMCS, including, but not limited to, transfer or
voting of any of the securities, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, division of profits or loss,
or the giving or withholding of proxies.


Item 7. Material to be Filed as Exhibits
        --------------------------------
