How many Internet users are in the United States?

Computer magazines are about computers and related subjects, such as networking and the Internet. They are popular in advanced countries. Most computer magazines offer advice, some coding instruction, reviews of the latest technologies, and advertisements. Computer magazines used to contain type-in programs, but these have gone out of fashion. Some printed computer magazines include floppy disks, CD-ROMs, or other media as inserts; they may contain software, demos, and electronic versions of the print issue. Many computer magazines are issued only on disk with no printed counterpart; such publications are known as disk magazines and are listed separately.
