Sure, I'd be happy to explain it in a simple way!

Imagine you have a lemonade stand. Here's what happened:

1. Your friend (SK Telecom) and another person (Samsung) wanted to buy your lemonade stand together.
2. They both put some money into it - $40 million each, which is like a big stack of pennies!
3. Now, they own the lemonade stand together. Your friend has 50% ownership because he also put in half the money.

So, when people talk about SK Telecom investing in a game company (Nexon Korea) with Samsung, it's just like our lemonade stand example! They're working together and investing money to become owners of that company. It's like they're saying "We believe in this game company and want to help it grow!" Read from source...
