The style of TV that most North Americans over 20 years old grew up with may still be hanging on, with popular shows like Lost, Glee and Modern Family doing extremely well for their respective networks. But in the last decade or so, there has definitely been a power shift. Scripted shows, with continuous stories and character development that require teams of writers and set designers, have been pushed to the back seat. Now riding shotgun are multiple-baby families, racially stereotyped pastry chefs and bug eaters.

In Pictures: 7 Millionaires By Marriage

Reality TV shows have practically dominated network and cable TV in recent years, but do these channels really benefit by airing wedding-hungry brides and toddlers in talent shows? The payoff is in the high revenue return and simple production value. Plus, it's difficult to discredit the entertainment value of an overweight, naked gay man who traipses off of a Borneo beach with $1 million, and eventually lands in prison.

The Price of Talent
Reality TV shows aren't cheap to produce. E! Online reports that a 30-minute reality show costs approximately $100,000-$500,000 per episode. This is in comparison to many scripted shows, for which the budgets can rival major movie releases.

But there are certainly differing factors to consider when comparing the production costs of reality TV shows and scripted ones. Naturally, reality TV shows require fewer writers. However, this role is not completely eliminated - how else would we be treated to such timeless moments as Hulk Hogan and his family taking a daytrip to a hair restoration clinic, while a plastic Hollywood doctor scribbles on The Hulkster's dome?

This is one of the main reasons networks prefer reality TV - the cost of non- (or aging) celebrities far undercuts that of established or current ones. Sarah Palin's proposed reality show will reportedly explore "her" Alaska, from the former Governor's own perspective. Her asking price per-episode is $1 million - that's as much as James Gandolfini was earning per episode near the end of The Sopranos run.

To put that price into perspective, the previously unknown stars of MTV's "Jersey Shore," which was the highest-rated cable series for its demographic at the time, earned a few hundred dollars per episode each. Though they will likely be making more in the upcoming season, even the reported $10,000 they had each been making per episode is dwarfed by the salaries made by actors in a scripted series. Charlie Sheen, for example, was earning $860,000 per episode on his hit show, "Two and a Half Men," in 2009.

Smaller Networks & Channels
This cost advantage spills over into the smaller and emerging networks - many of which wouldn't exist without the low-cost advantage of reality TV. There are even two channels dedicated solely to reality TV: Fox Reality in the U.S., and Zone Reality in the U.K. Not mentioning MTV, which had a massive resurgence in the 2000s thanks to the format, Bravo, Spike TV and TLC are all channels that owe much (if not all) of their current successes to octomoms, little people and realtors hungry for a slice of fame.

TLC was even rebranded with "Life Unscripted" as its slogan in the mid-'90s, "Live and Learn" in the mid-2000s and "Life Surprises" in the late-2000s. Since undergoing this rebranding, the channel has shaken its poor ratings and has become one of the primary sources for reality shows. Undoubtedly, the success of shows like "Jon & Kate Plus 8" contributed to the recent surge in market price for TLC's parent company, Discovery, in 2008-2009.

The Perfect Placement
As well, product placement is much easier to digest in reality television. This practice, which generates advertising revenue for both the show and the network, hasn't been as prosperous for scripted TV shows. The reigning king of reality TV ratings, American Idol, dedicates entire skits during its show to Ford Motor Company, AT&T Mobility and Apple iTunes. Survivor contestants are regularly rewarded with Snickers chocolate bars and Doritos nacho chips. This in-show placement accompanies regular commercial breaks, and increases the value of advertisement for sponsors.

Staying Power
Initially, networks were concerned with the post-season marketability of reality TV shows. Syndication revenue and retail sales of DVDs can generate more income for a TV show than its initial run, and the timely nature of these shows presented a red flag in marketing departments across the board, as it relates to post-season earnings. But when DVDs for shows like "The Simple Life," "The Amazing Race" and "America's Next Top Model" (to name just a few) outranked and outsold network dramas like "Desperate Housewives" and "The O.C." on, those fears were eased.

Reality Unscripted
At the end of the day, the biggest advantages reality TV shows have over scripted ones are financial, but that's no surprise. Also, the fact that reality shows are often used to deliver new content (and bring in ad money) while comedies and dramas are "off-season" is a major benefit. By filling the majority of a calendar year with "new" episodes of a show, networks and cable channels can capitalize on ad revenue for a longer time span - and there's little fear that a union strike will cease production in the meantime.
