Create video streaming website like Netflix requires excellent security, large bandwidth, and a limitless supply of content. For example, if a user wants to watch a movie, the video streaming website will have to connect to a server that has the movie stored, and then stream the video through to the user.  Thus, if your video streaming website is slow to stream content, security is weak, or if the server is down, then you will not be able to compete with the DVD industry. Furthermore, you would need a large amount of content to stream, but people will still want the full movie experience that they get from watching a DVD. Although the DVD industry is in decline, the only way to compete with them is to become the leading video streaming website.
