How are fake reality shows not false advertising? And if they are, why do they get away with it?

Wikipedia defines Reality Television as:

"Reality television is a genre of television programming that documents unscripted situations and actual occurrences, and often features a previously unknown cast. The genre often highlights personal drama and conflict to a much greater extent than other unscripted television such as documentary shows. The genre has various standard tropes, such as reality TV confessionals used by cast members to express their thoughts, which often double as the shows' narration. In competition-based reality shows, a notable subset, there are other common elements such as one participant being eliminated per episode, a panel of judges, and the concept of immunity from elimination."

And further down, still in the overview, wikipedia also includes:

"Reality television has faced significant criticism since its rise in popularity. Much of the criticism has centered around the use of the word "reality", and such shows' attempt to present themselves as a straightforward recounting of events that have occurred. Critics have argued that reality television shows do not present reality in ways both implicit (participants being placed in artificial situations) and deceptive or even fraudulent, such as misleading editing, participants being coached in what to say or how to behave, storylines generated ahead of time, and scenes being staged or re-staged for the cameras. Other criticisms of reality television shows include that they are intended to humiliate or exploit participants (particularly on competition shows), that they make celebrities out of untalented people who do not deserve fame, and that they glamorize vulgarity and materialism."

Wikipedia defines False Advertising as:

"False advertising or deceptive advertising is the use of false or misleading statements in advertising, and misrepresentation of the product at hand, which may negatively affect many stakeholders specifically consumers. As advertising has the potential to persuade people into commercial transactions that they might otherwise avoid, many governments around the world use regulations to control false, deceptive or misleading advertising. "Truth" refers to essentially the same concept, that customers have the right to know what they are buying, and that all necessary information should be on the label.

False advertising, in the most blatant of contexts, is illegal in most countries. However, advertisers still find ways to deceive consumers in ways that are legal, or technically illegal but unenforceable."

So I've been curious about this for a while. How are shows like Jersey Shore and Duck Dynasty (among many other proven to be scripted shows) allowed to be advertised as Reality Television when they in fact don't meet the criteria at all and are merely "themed" as Reality Television at best? The Reality TV theme of these shows shouldn't justify their advertisement as actual Reality Television any more than mocumentaries like The Office.

I know many viewers of these kinds of shows that actually think it's real (and rightfully so, it's advertised officially as Reality Television). It's a significant marketing factor. If all their viewers knew it was in fact staged and scripted, I'd predict their viewer count would drop dramatically. Essentially they're profiting off of their lie (False Advertising).

So what's going on here? Why are they allowed to do this?
