VSN - Before it was finally called Metaverse, in 2010, David Siegel wrote a book about it. David consults on digital acceleration and the semantic web, especially Metaverse. David defines Metaverse as the real-time location-aware web. He describes the connected worlds in Metaverse, like the power strip in Wreck-It-Ralph, where the characters from one game could enter several other games. David also noted that Metaverse gives new forms of collaboration for companies, digital assistants, and open markets.
