The Australian Competition and Consumer Commission will not intervene in Google Inc's proposed acquisition of DoubleClick Inc., ACCC Chairman, Mr Graeme Samuel, said today.

Google sells advertising space on its own websites as well as on third party websites and owns the leading internet search engine in Australia. DoubleClick develops software that allows publishers and advertisers to display, or 'serve', graphical advertisements onto websites.

"The ACCC carefully considered the likely effects of the proposed transaction on the Australian online advertising industry," Mr Samuel said.

"A key focus of the ACCC's investigation was whether the combination of Google's network of website publishers and DoubleClick's ad serving capabilities would enable the merged entity to increase the cost of ad serving to website publishers and advertisers.

"In reaching its decision, the ACCC noted that Google and DoubleClick are not close competitors in the provision of ad serving. In addition, the ACCC also took into account the presence of other competitors in this market that would be likely to constrain the merged entity post-merger.

"In this context, the ACCC considered that the merger was unlikely to result in a substantial lessening of competition in an Australian market."

A Public Competition Assessment of this matter will be available in due course at www.accc.gov.au/mergers/
