Microsoft Corporation and Yahoo! Inc - proposed search engine agreement


  • Microsoft Corporation


  • Yahoo! Inc


Microsoft Corporation and Yahoo! Inc. proposed to enter into an agreement to combine their search and search advertising businesses. Under the proposed transaction, Microsoft would acquire an exclusive licence to Yahoo! search technologies for a period of 10 years. The transaction also involved Yahoo!'s existing search technology being integrated into Microsoft's Bing search engine (the Bing search engine will 'power' Yahoo!'s search engine) and Yahoo! becoming the exclusive worldwide relationship sales force for both company's premium search advertisers.

Market definition

The ACCC considered the competitive effects of the proposed agreement in the context of national markets for:
- the supply of online paid search advertising; and
- the supply of online search syndication services.
As the proposed agreement between Microsoft and Yahoo! related only to online search advertising, the ACCC did not consider the national market for the supply of online display advertising.

Competition analysis

The ACCC considered that the proposed agreement was unlikely to result in a substantial lessening of competition in the relevant markets. Factors informing this conclusion included:
- Microsoft and Yahoo! had an existing relationship in Australia, in which Microsoft utilised Yahoo!'s paid search platform. Therefore, Microsoft and Yahoo! through their respective Australian subsidiaries - ninemsn and Yahoo!7 - did not compete for paid search advertising in Australia;
- Microsoft and Yahoo!'s share of online paid search advertising queries in Australia was limited. In combining search engine platforms, Microsoft and Yahoo! may have been able to achieve the necessary scale to provide effective and sustainable competition to Google, which had a very large share of online paid search advertising queries; and
- the proposed agreement did not appear to decrease innovation incentives for either of Microsoft, Yahoo! or Google.
