The evolution of Google

IN 1998, a search engine from an obscure startup launched. It featured a logo, a text field, and buttons for search and “I’m Feeling Lucky” — and not much else. Its name was Google, and it changed the way that the world interacted with information.
It’s tempting to think of Google search as something that hasn’t evolved radically over the years, in part because the Google.com homepage hasn’t changed much. Under the surface, however, Google has changed plenty, in increasingly profound ways and if the company’s ambitious plans pay off, the Google of just a few years from now could be a new kind of search engine.
