The advent of video technology in the 1980s encouraged the development of many cheap exploitation movies. Exploitation movies are movies made about a popular but controversial subject. The Vietnam War was one of the greatest examples, and many low-quality films were about the Vietnam War to capitalize on the controversy and interest in its subject matter.
Today, many of these movies are on YouTube, due to their rarity on home video and the lack of interest of their owners in enforcing copyright. However, many studios made truly great Vietnam War movies, such as Francis Ford Coppola's "Apocalypse Now," Stanley Kubrick's "Full Metal Jacket" and Oliver Stone's "Platoon," which won the 1986 Academy Award for Best Picture. These, and other acclaimed Vietnam War movies, are occasionally posted on YouTube but are frequently removed for copyright infringement. This is because their owners still make a significant profit due to the acclaim and popularity of their films.
Many Vietnam War films are available to stream on services such as Netflix, Hulu Plus and Amazon Prime.
