Until now, a Google search for “I have a dream” would have returned links to the text of the 1963 speech by the Rev. Dr. Martin Luther King Jr. and to other historical and informational Web sites about him. But those looking for video clips or photographs of Dr. King’s speech would have had better luck by entering a query in Google’s specialized services for video or image searches.
The same query on Google’s main service will now return a single list of results that will blend text, videos, images, and even excerpts from books. The list will appear in the order that a Google formula deems to be most relevant.
