In 2000, Google Search results had been limited to simple pages of text with links. Google's developers worked on developing this further, and they realized that an image search tool was required to answer "the most popular search query" they had seen to date: Jennifer Lopez in her exotic green Versace dress. As a result of this, Google Image Search was launched. By 2001, 250 million images were indexed in Image Search. This number would eventually grow to 1 billion images by 2005 and 10 billion by 2010.
