Smart TVs grew in popularity as an alternative to 3D TVs, which consumers did not widely adopt. Smart TVs connect to the internet through various ports and cables, allowing interactive features like apps and targeted advertising. While more capabilities offer more opportunities for hacking, higher resolution 8K TVs that display 4 times as many pixels as 1080p are starting to be produced but come with high costs and require high-spec infrastructure to view 8K content.
