Google's AdWords

Google's AdWords

AdWords is Google's flagship advertising product and main source of revenue ($16.4 billion in 2007)[1]. AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.

Google's AdWords division is based in Ann Arbor, Michigan[2], the company's third-largest facility behind its Mountain View, California, headquarters and New York City office.[3]
This is a list of acquisitions by Google, a computer software and a web search engine company. Each acquisition is for the respective company in its entirety, unless otherwise specified. The acquisition date listed is the date of the agreement between Google and the subject of the acquisition. The value of each acquisition is listed in US dollars because Google is headquartered in the United States. If the value of an acquisition is not listed, then it is undisclosed. If the Google service that is derived from the acquired company is known, then it is also listed.
Google's largest acquisition as of March 2008 is the purchase of DoubleClick, an online advertising company, for US$3.1 billion. Because of the size of the acquisition, United States antitrust regulators took nearly a year to investigate the deal and clear it for approval. The majority of the companies acquired by Google are based in the United States, and in turn, a large percentage of these companies are based in or around the San Francisco Bay Area. A total of 51 companies have been acquired as of March 2008.
