Adobe Systems (commonly known just as Adobe) is a software empire.
They make some good programs Photoshop which is a well known graphics editor, it is used to edit pictures and to make them with many detail and options to choose from. It is very popular among the image creating/editing community.
Unfortunately Adobe Systems practically have a monopoly in the computer graphics software industry.  The US government were dumb enough to let them buy the defunct software company, Macromedia in 2005 which allowed Adobe to gain a monopoly in the graphics editing world.
