Editing RGB color model (section)

===Personal computers===
[[Personal computer]]s of the late 1970s and early 1980s, such as the [[Apple II]] and [[VIC-20]], use [[composite video]]. The [[Commodore 64]] and the [[Atari 8-bit computers]] use [[S-Video]] derivatives. [[IBM]] introduced a 16-color scheme (4&nbsp;bits—1&nbsp;bit each for red, green, blue, and intensity) with the [[Color Graphics Adapter]] (CGA) for its [[IBM Personal Computer|IBM PC]] in 1981, later improved with the [[Enhanced Graphics Adapter]] (EGA) in 1984. The first manufacturer of a [[24-bit color|truecolor]] graphics card for PCs (the TARGA) was [[Truevision]] in 1987, but it was not until the arrival of the [[Video Graphics Array]] (VGA) in 1987 that RGB became popular, mainly due to the [[analog signal]]s in the connection between the adapter and the [[computer monitor|monitor]] which allowed a very wide range of RGB colors. Actually, it had to wait a few more years because the original VGA cards were palette-driven just like EGA, although with more freedom than VGA, but because the VGA connectors were analog, later variants of VGA (made by various manufacturers under the informal name Super VGA) eventually added true-color. In 1992, magazines heavily advertised true-color Super VGA hardware.
