Or rather flow TV is not the term consumers should use, as it more accurately describes how broadcasters try to capture and retain an audience by keeping it from changing channels or doing something else.
As a consumer, “flow” should conjure the image of being caught in a stream (no pun intended) which tries to carry you away against your will.
I think I understand the term as it was originally used in studies in USA, and I think it is somewhat more appropriate to the way American television is constructed.
“Scheduled TV” would be a better term, if you want to describe it from the consumer point of view.
This is then added to one of my pet peeves, along with responsive web design, which isn’t responsive at all. It is adaptive, adapting to the device of the consumer. Unless of course the response you are looking for is to people changing the size of their browser windows.
