One reason "reality" TV
is so popular is cost. Reality is cheap.
Here in America, when sitcoms ruled the airwaves if a show was popular the actors/actresses would eventually start demanding six figure incomes. Look at what happened to "Freinds". Reality TV
does not use actors or actresses, they use regular people who they have to pay little or nothing to. Money saved.
They also don't have to build sets, "reality" locations are already built so money is saved. "Reality TV
" is a cash cow that the networks are going to milk to death. More money saved.
The audience (viewers) like reality type shows, they watch ratings go up and sponsors pay big bucks to advertise on these shows.
Next season we will have tons more reality shows than we do now. But the end may be in sight. Popular directors of the better reality shows are in high demand, and their salaries are going up. They are asking for more and more. It won't be too much longer before people start asking for more to be on these shows and then the people who own the locations will realize that there is money to be made and will start asking for more in "location fees".
I give it three more years before "reality" starts to fade...
