What is pewdiepies first name

Who could someone say who's pewdiepie????? Ugh!!! Don't people watch YouTube anymore?!?!?!

@Hunger games addict Sam

i have a question on this matter on my profile

I love pewds! I watch every single video of him

How could someone not know who he is. He is the most subscribed youtuber. Even my sister who doesn't care for gaming still knows who he is.
