Nintendo released a series of arcade games in the 1970s and 80s. The company made toys and trading card games prior to their film projection-based light gun games from 1973 to 1978. Nintendo released its first electronic arcade game in 1978, an adaptation of the board game Reversi. Many of Nintendo's first video games were knockoffs, or "clones", of existing games with slight variations, including Breakout clones and clones of Space Invaders and Galaga. Nintendo also successfully released its first Japanese home consoles, the Color TV series, which brought arcade games to personal televisions.
