Does Las Vegas pay people off to say good things about them in the media, TV shows, and movies?

I’m going to give some examples here where they act like they’re trying to kiss Las Vegas’s as# by how good they try to make it sound,…

1. TV Show “Fresh-Prince of Bel-Air”(Carlton acts so happy and excited about Las Vegas even after he loses all of his money)
2. TV Show “Married with Children”(Peg and Marcie love the place, and after Al wins $10,000 from lasting 3 minutes with a big woman in a wrestling match, they take all his money and want to spend more of it in Las Vegas
3. TV Show “Full House”(They say positive things here and there in the show, Joey Gladstone’s all like happily gambling and Steph and DJ win a big jackpot on just one spin, very unlikely)
4. Movie 1994 “City Slickers 2 Legend of Curly’s Gold”(Near the end Billy Crystal says how people love to come for the $1.99 all you can eat buffets)
5. Movie 1997 “Vegas Vacation”(Don’t even get me started on this one. These are countless scenarios where Chevy Chase and the rest make Las Vegas seem fantastic and Russ(Papa Gorgio) wins a car after just one spin. The only voice of reason was Audrey when she said at the beginning how there’s nothing to do there. Nothing to do but gamble, she was right.
6. Movie 2008 “What Happens in Vegas”(When they want a vacation, their best friend tells them where they need to go for fun, where all their troubles melt away, and it being Las Vegas)
7. Movie 2009 “Last Resort”(One of them screams “We should’ve went to Vegas!”) Really? I’d rather go to a place for fun, like DisneyWorld or Alaska for the wildlife.
8. Many, MANY online gambling articles saying how slots are great fun, when we all know that just isn’t true. The odds of those slots are a laughable joke, but Vegas doesn’t want you knowing that.

Seriously, how much does Las Vegas pay those people off?
They must be paying them off or else they wouldn’t sound all that positive.
