Cable, fibre optic, the internet, satellite, antennae, etc. are all means of delivery of content.
Content can be news, movies, scripted shows, reality shows, game shows, amateur movies, situation comedies, etc.
Content Providers are Verizon, AT&T, Netflix, Roku, Apple TV, etc.
Content Producers are NBC, ABC, HBO, CBS, etc. plus dozens of movie and media studios.
Television simply refers to how you are viewing the content (as explained by @rebbel).
The confusion comes in that the word “television” has also come to be known as the box with the screen in your house. But really, it’s a “television set”.
Same as a “radio” is really a “radio receiver” that translates “radio waves” carrying content to the listener.
So (short answer) – YES it is still television in my opinion.
