Vodafone, MTV2 and Ikea are among the companies that have resurrected previous incarnations of their websites as part of 'archaelogicial dig of the web'.

The websites form part of an exhibition called Digital Archaeology, which has been launched to celebrate the web's 20th anniversary, and will be on display in Shoreditch, London, until November 12th.

The exhibition has been put together by Jim Boulton of digital content agency Story Worldwide and is part of Internet Week Europe, which takes place in London for the first-time this week. The exhibition also includes video clips of interviews with the brains behind the sites on display.

According to Boulton, since the internet's invention in the early 1990s organisations of all shapes and sizes have updated their websites, sometimes numerous times each year, or launched completely new versions to market.

"With every update or new site, the old version is effectively removed from the web, unable to be traced online from that point onwards, and most often stored on disappearing hard drives and redundant servers belonging to the digital artisans who first created them, never to be seen again," he said.

"Artistic, commercial and social history is being wiped from the face of earth. In five years time or so, I doubt websites will exist and I expect the vast majority of sites from the first twenty years of the web to be gone forever."

Web users can also visit a dedicated website and submit their own views on other sites that need to be resurrected. From these suggestions, Boulton and his team will then choose the next set of websites to unearth in the coming months.

""The sites showcased at Digital Archaeology were the result of a DIY culture in offices that didn't have the glitz and glamour that many of the global web businesses of today enjoy" he said.
