An anonymous reader writes "Google has issued a statement on the Inside AdWords Blog. Based on the thoroughness of the statement and the use of the word 'precedent' in the second sentence, it appears that the Google PR team huddled with the legal team to get their point across."
From the post: "Being rather proud of AdWords as a means to effectively advertise one's products or services, it seems natural to use it ourselves. Since it's a common practice across the industry for companies to promote their own products and services through their own web presence, there is much precedent to do this. It's important to note, however, that our ads are created and managed under the exact same guidelines, principles, practices and algorithms as the ads of any other advertiser. Likewise, we use the very same tools and account interface."
