 Unlike smaller, independent video stores, these large video stores cultivated a "family friendly" image and did not stock pornography, but the need arose for them to provide adult entertainment to a large customer base of couples who watched movies together.By the late 1980s these two new markets, together called direct-to-video, or DTV, had become a lucrative, non-theatrical alternative for producers of low-budget, R-rated films.A film that served as a prototypical success and catalyst in this new market was "Night Eyes" (1990), the story of a security guard who falls in love with the married woman he is hired to both protect and electronically surveil.
