Microsoft Corporation - proposed acquisition of aQuantive Inc


  • Microsoft Corporation


  • aQuantive Inc


NASDAQ listed software developer, Microsoft Corporation (Miscrosoft), sought to acquire aQuantive Inc. (aQuantive), a digital media company.

Market definition

In Australia, Microsoft's subsidiary, Microsoft Pty Ltd, has a joint venture with PBL Media that trades as Ninemsn. Ninemsn provides space for search and non-search advertising on its website It does not provide space for classified or directory advertising.

In Australia, aQuantive's subsidiary, Amnesia, develops targeted marketing strategies to maximise the ability of advertisers to reach target audiences on the internet.

Therefore, the ACCC considered that the most likely relevant markets were likely to be, broadly, the markets for:
* the provision of advertising space; and
* the provision of advertising services to advertisers.

It was not necessary to come to any definitive conclusions on market definition, however, because even on the narrowest definition of the relevant markets the ACCC considered that competition concerns were unlikely to arise.

Competition analysis

The acquisition resulted in the vertical integration of Ninemsn's role as a seller of online advertising space, with aQuantive's role as a provider of online marketing services to advertisers.

The ACCC found that there are a significant number of well-resourced firms operating at both the upstream advertising space market and the downstream online advertising services market that would be likely to constrain the behaviour of the merged entity post-acquisition. Therefore, the ACCC considered that the merged entity would be unlikely to be able to exercise market power in either market post-transaction. Accordingly, the ACCC considered that the proposed acquisition was unlikely to substantially lessen competition in the relevant markets.
