What 4K content is available?
When 4K TVs were first introduced, there was not much 4K content to watch. This caused some consumers to hesitate purchasing the TVs. Now there's so much 4K content available that it's no longer an issue.
Currently, there are various forms of 4K content from 4K broadcasting, 4K streaming services, 4K Blu-ray players & discs to even UGC videos filmed with 4K cameras or 4K smart phones. There are approximately 80 channels worldwide that broadcast in 4K (according to Wikipedia), and VoD services such as Netflix, Amazon Prime, Vudu and Rakuten also offer a wide range of contents such as 4K movies and TV series. Plus, if you have a 4K Blu-ray player you can easily purchase and enjoy 4K videos from places like Amazon.com.
Recently, a lot of people enjoy filming videos using 4K cameras or smartphones with 4K cameras built in and share that content with other users through video sharing platforms such as YouTube and Vimeo. So, feel free to explore whatever catches your interest.
