Okay kiddo, do you know what a burger is? It's a tasty sandwich made with a meat patty, sometimes with cheese and vegetables on a bun. Yum! Well, sometimes different companies that sell burgers try to outdo each other by making better, tastier or cheaper burgers than their rivals. This is called the "burger wars".
So, imagine that you own a burger shop, and you want to sell more burgers than the shop across the street. You might make your burgers bigger or put more toppings on them. Or you might lower the price so that people choose your burgers instead of the other guy's.
But wait, there's more! Sometimes, burger companies spend a lot of money on advertising to convince people to buy their burgers instead of their competitors'. They might make funny commercials or have famous people in them. They might even use social media to try and get more people to follow their brand.
So, that's what burger wars are, the competition between different burger companies to sell more burgers and become the most popular. But don't worry, you don't have to choose sides - you can always try every burger and decide for yourself which one you like the best!
