One of the main reasons why VPNs are so popular is because of their ability to unblock geo-restricted access.

In other words, they let you access content that you wouldn’t otherwise be able to reach due to your location, such as getting the US Netflix in the UK (with all its extra content). Some countries block Netflix completely, of course – for example, China – and again, you can use one of the best VPNs to get around this.
