The functions embedded into "screens" have changed dramatically over the last three decades. In the past, the TV was a moderately dumb device, while the component TV monitor intentionally was a dumb device.
With the introduction of smart phones, iPods, game players, tablets and notebooks, most screens are part of "intellligent" devices that make quite a few specific assumptions about the networks and types of software those devices will be interworking with and supporting.
With the exception of the desktop PC monitor, virtually all other screens intentionally assume roles as "intelligent" devices, with specific networks and application environments in mind.
These days most TVs remain moderately intelligent screens that still require some third party devices to add more functionality. For cable, satellite and telco TV, that device is the set-top decoder. In other cases it is the game console or an "Apple TV" box that provides the additional functionality.
The big issue now is how fast, and how far, the third party functionality can be built into the standard TV. Up to this point, it has proven quite difficult to do so, and that likely will not change, even as rumored Apple TVs and Google TVs are created for the mass market.
The point is that many of the advanced features still require highly network-specific software loads that cannot all be supported in a basic TV display.
That is important because advanced features that can be "built in" to a smart phone or tablet will be more difficult in a TV monitor.
Each smart phone is built with detailed knowledge of the networks it must interoperate with.
Many third party devices, such as game consoles, simply cannot make those assumptions and must be insulated from network details, with the exception of simple network interfaces, such as Wi-Fi and Internet.
The big question for any new suppliers that want to change the experience of TV viewing is to determine which important new features can be embedded, at what cost. In most cases, a relatively "dumb" approach still will make sense for general purpose screens that are expected to work with "all" game consoles, service provider decoders, VCRs, DVD players and video recorder devices.
Though service providers long have wanted an ability to offload the decoder functions to the TV, that has proven impractical. In most cases, especially when software continues to evolve rapidly, it will make sense to provide standard network interfaces to popular third party devices, Internet and Wi-Fi connections, while restricting on-board applications and features that typically are provided by a third party device.
Many would argue TVs always will have to be relatively dumb displays, compared to other screens, because those other screens are designed to be used primarily within one platform, or on one network. But nobody wants to get a new TV every time they change video service providers, game consoles or other devices that normally get attached to TVs.

Evolution of the "Screen"
Gary Kim has been a digital infra analyst and journalist for more than 30 years, covering the business impact of technology, pre- and post-internet. He sees a similar evolution coming with AI. General-purpose technologies do not come along very often, but when they do, they change life, economies and industries.
