Do you familiar with this topic
Did you mean Big Brother? Yeah, I watch it all the time, although only in the US. I don't think I'd be able to watch all 387 seasons!
oh I see, can you tell me about it
Sure! It's basically a reality game show. It was originally broadcast in the Netherlands but became so popular it was aired internationally.
oh! that's nice, what was the game about
Contestants called "housemates" live together in a house built just for the show. It's isolated from other people, and their actions are all filmed on camera.
thank you, now I got some idea about the show 
Well what's even better is these contestants will vote to evict other players. The last one who remains is the winner!
oh! that was amazing, Do you like the show
I do enjoy watching. It has gotten kind of more exciting recently as they have more methods of voting now, such as using social media or smart devices.
