There was a time - and not that long ago, either - when if you wanted to see a film you would have to go to the theater to enjoy it. As time went on, the possibility of watching a movie of your choice was augmented into the home by the development of video players, which would let you either buy or rent a movie for the purpose of watching on your home television - but the difference in picture quality between the video and the cinema screen, among other issues, was so vast as to be astonishing.
At present, it is impossible for anyone but the incredibly rich to get the same movie-watching affect in their home as they would in a theater. Only those who can afford to acquire and host a cinema screen and the proper projecting equipment can do that. Nonetheless, now it is more imaginable than ever that you can sit and watch a movie in the way that the director, producer and the rest of the technicians working on the film really intended, and this is a result of the creation of large-screen televisions and DVD technology.
Of course, there is a vast range of equipment available that runs from the bargain-priced but technically limited to the state-of-the-art home entertainment systems that will set you back a lot more money. The line is still in what you can buy, but home entertainment in the current day is now closer than ever to the quality that you could approach in a cinema.
