There's no denying that, for most people, streaming is the future of watching movies, what with home video sales sharply declining year upon year.
But for anyone who grew up in the late 1990s or early 2000s, there's no mistaking the sheer cultural impact of the optical media revolution.
DVD and later Blu-ray not only marked a major uptick in visual fidelity from VHS, but also allowed the inclusion of extra features, from deleted scenes to bloopers, featurettes, audio commentaries, and even Easter eggs too.
It was extremely common for DVDs to include sneaky hidden clips and features for savvy customers to discover - or if you wanted to take a shortcut, just sift through all the video data on your PC.
The art of DVD Easter eggs may be long gone, but for fans of the medium, it's anything but forgotten, and perhaps no single genre has made better use of it than horror.
Whether you needed to input a code, locate a secret menu hidden on the main menu screen, or find a subtle interactive trigger, these extras rank among the most creepy, weird, hilarious, and even fascinating you're ever likely to see on home video...
10. Saw In 60 Seconds - Saw
The original Saw film was made on a shoestring budget compared to most studio horror flicks, and the movie's DVD release included a playful, albeit secret homage to that.
The second disc of the Saw Uncut DVD release contains a "Cut Media" menu, which features images of a number of torture devices used throughout the film.
If you select the chain and shackle and then press up, you'll highlight a hidden "X", in reference to "X marks the spot" scene from the movie itself.
Select the option and it'll take you to an additional menu where you can select a feature called "See Saw in 60 seconds."
This will load up a video clip in which the entire plot of the movie is played out with dolls, accompanied by dialogue from the movie itself, inside of a square minute.
There's no word on whether filmmakers James Wan and Leigh Whannell came up with this themselves, but it's a neat little hidden extra all the same.
