Tim Berners-Lee's account of the exact locations at CERN where the Web was invented, is here.

On August 6, 1991, Berners-Lee posted a short summary of the World Wide Web project on the alt.hypertext newsgroup. This date also marked the debut of the Web as a publicly available service on the Internet.

The WorldWideWeb (WWW) project aims to allow all links to be made to any information anywhere. [...] The WWW project was started to allow high energy physicists to share data, news, and documentation. We are very interested in spreading the web to other areas, and having gateway servers for other data. Collaborators welcome!" —from Tim Berners-Lee's first message

More conventional retailers found online merchandising to be a profitable additional source of revenue. While some online entertainment and news outlets failed when their seed capital ran out, others persisted and eventually became economically self-sufficient. Traditional media outlets (newspaper publishers, broadcasters and cablecasters in particular) also found the Web to be a useful and profitable additional channel for content distribution, and an additional vehicle to generate advertising revenue. The sites that survived and eventually prospered after the bubble burst had two things in common; a sound business plan, and a niche in the marketplace that was, if not unique, particularly well-defined and well-served.
