Google URL Index Hits 1 Trillion

We knew the web was big...

7/25/2008 10:12:00 AM

We've known it for a long time: the web is big. The first Google index in 1998 already had 26 million pages, and by 2000 the Google index reached the one billion mark. Over the last eight years, we've seen a lot of big numbers about how much content is really out there. Recently, even our search engineers stopped in awe about just how big the web is these days -- when our systems that process links on the web to find new content hit a milestone: 1 trillion (as in 1,000,000,000,000) unique URLs on the web at once!

How do we find all those pages? We start at a set of well-connected initial pages and follow each of their links to new pages. Then we follow the links on those new pages to even more pages and so on, until we have a huge list of links. In fact, we found even more than 1 trillion individual links, but not all of them lead to unique web pages. Many pages have multiple URLs with exactly the same content or URLs that are auto-generated copies of each other. Even after removing those exact duplicates, we saw a trillion unique URLs, and the number of individual web pages out there is growing by several billion pages per day.

GigaPan

GigaPan is the newest development of the Global Connection Project, which aims to help us meet our neighbors across the globe, and learn about our planet itself. GigaPan will help bring distant communities and peoples together through images that have so much detail that they are, themselves, the objects of exploration, discovery and wonder. We believe that enabling people to explore, experience, and share each other's worlds can be a transforming experience. Our mission is to make all aspects of the GigaPan experience accessible and affordable to the broadest possible community.

GigaPan consists of three technological developments: a robotic camera mount for capturing very high-resolution (gigapixel and up) panoramic images using a standard digital camera; custom software for constructing very high-resolution gigapixel panoramas; and, a new type of website for exploring, sharing and commenting on gigapixel panoramas and the detail our users will discover within them. The GigaPan website allows hosting and sharing all kinds of panoramas, and so the robotic GigaPan mount is recommended but is certainly not required to be part of this community.

'Dark Knight' sets opening weekend box office record

A Warner Bros. executive says the Batman sequel "The Dark Knight" has taken in $155.34 million to top "Spider-Man 3" for best opening weekend ever at the box office.

The figures released Sunday show "The Dark Knight" more than $4 million ahead of the $151.1 million first weekend for "Spider-Man 3" in May 2007.

Studio distribution chief Dan Fellman says "The Dark Knight" also broke the "Spider-Man 3" record for best debut in IMAX large-screen theaters with $6.2 million. "Spider-Man 3" opened with $4.7 million in IMAX cinemas.

Stoked by fan fever over the manic performance of the late Heath Ledger as the Joker, "The Dark Knight" also set a one-day box office record with $66.4 million on opening day, Fellman said Saturday.

The movie's Friday haul surpassed the previous record of $59.8 million set last year by "Spider-Man 3."
