Sources of Profit are changing
Name
The sources of profit are changing in TV industry. As I analyzed in the research questions concerned with profit, the traditional ways of earning revenues in TV is advertisement, to be exactly, one way advertisement that audience in front of TV set passively accept whatever is showing on TV. Such kind of advertisement is confronted with a downside profit earning, that old TV industry can't back up itself with one way advertisement for a long time in the future. New profits may catch audience's eyes from television to other medias, like Internet TV, where the profits can be explored.
Enablers
Inhibitors
It could be other channels existing or potentially emerging that also provide interation with audience. For example, mobile TV is an alternative, which allows users to watch TV and provide fee of commertial services directly through mobiles. Even the enjoying feeling of watching TV can't be regarded the same as watching real TV through television set or PC, the convience and mature payment network exceed the situation in Internet TV. Whatever, mobile TV and Internet both need more technical maturity and market acceptance.
Paradigms
Innovative forms of profit are created based on more variable medias. Advertisements are diversified and audience participate and enjoy commertials while disclose their preference to ad makers and marketers to provide them more opportunities for new profit sources creation.
Experts
Supported by front edge advertisement makers, who are running interactive commertials to get large margin.
Timing
The change in profit resources is under way nowdays. It is probable within a few years that a quite larger amount of advertisements is distributed through more variable medias and in the form of two way communications.
