Internet media company Yahoo says it is buying California-based search engine Overture Services for more than $1.6 billion.
Yahoo said Monday the combined companies will provide the "most compelling and diversified" group of integrated marketing solutions in the world. Overture, formerly known as GoTo.com, sells advertising space on Yahoo and other Internet search engines.
Yahoo, which also is based in California, has popular sites for shopping, regional interests, and news and entertainment.
