So the image and sound quality achieved today is incredible, and technology has advanced so much that we have access to a variety of resources, such as internet access, on-demand content, among other features. In addition, evolution has also brought thinner, lighter and more economical televisions.
But despite the changes in television technology, it is important to remember that these advances are not accessible to everyone, which reinforces the need to think about solutions that democratize access to these technologies. However, it is undeniable that technological innovations in televisions have improved the user experience and transformed the way we interact with programming.
