The Television Interface Adaptor (TIA) is the custom computer chip that is the heart of the Atari 2600 game console, generating the screen display, sound effects, and reading input controllers. Its design was widely affected by an attempt to reduce the amount of RAM needed to operate the display. The resulting design is notoriously difficult to program, but at the same time offers flexibility well beyond the capabilities of contemporary designs. It remains a key reason that the 2600 maintains a strong homebrew following.
Development of the TIA was led by Jay Miner, later of Amiga fame. Atari later expanded on the design of the TIA for the Atari 400 and Atari 800 with the CTIA and GTIA chips.

Famous quotes containing the word television:
“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
