When the concept of movies and cinemas first came out, the only way we could have access to them was to go to a cinema and watch them from there. This required us to have to leave our houses, and go out. Then came televisions and VCR sets, so by inserting a VCR disk, we were able to start watching movies in our homes, however, we would still end up having to pay for the VCR. The same principle applied to CDs, and you can still continue to buy CDs of different movies at any CD store.
Then came Netflix, a website that completely revolutionized the way we watched movies. With Netflix, all you need to do is sign up for an account, pay a fee every month, and then have access to thousands of movies online and continue watching them. Now, Netflix is a service that is only available in a number of countries, so not everyone else has access to its services.
This is where streaming websites like 0123movies.st step in and make things even more convenient. In order to watch a movie on any of these streaming websites, all you have to do is search to see if your desired movie is available on said website, and if it is available, you can simply start watching it by streaming it online. What makes streaming websites so popular is that you can access them from anywhere around the world, and a majority of these websites happen to offer free streaming services, so you do not have to spend any money either, allowing you to watch whatever you want to in the comfort of your own home. However, there are other websites that do happen to charge you for their services and ask you to create an account first.
