The only difference is that since the Street does not really exist—it's just a computer-graphics protocol written down on a piece of paper somewhere—none of these things is being physically built. They are, rather, pieces of software, made available to the public over the world-wide fiber-optics network. When Hiro goes into the Metaverse and looks down the Street and sees buildings and electric signs stretching off into the darkness, disappearing over the curve of the globe, he is actually staring at the graphic representations—the user interfaces—of a myriad different pieces of software that have been engineered by major corporations. In order to place these things on the Street, they have had to get approval from the Global Multimedia Protocol Group, have had to buy frontage on the Street, get zoning approval, obtain permits, bribe inspectors, the whole bit. The money these corporations pay to build things on the Street all goes into a trust fund owned and operated by the GMPG, which pays for developing and expanding the machinery that enables the Street to exist.
