In spite of total revenues going up from US$ 5257.67 million in 2005 to US$ 6425.68 million in 2006, Yahoo's net income fell from US$ 1896.2 million to US$ 751 million (Refer to Exhibit I for Yahoo's Income Statement between 2001 and 2006). According to analysts, the problem was that Yahoo was not focusing on any particular product, but was trying instead to cater to different customers through a single portal. Though Yahoo acquired several companies, it failed to integrate them. Even in search-related advertising, which had emerged as a major revenue generator in the Internet business, Yahoo fell behind its competitor Google, which was generating twice as much revenue on each search ad.
