I think by now, you all know that you can trace every single person I watch on YouTube through Zoella. I started watching Jim purely because he's Tanya Burr's then boyfriend (now husband).
Jim started out doing a lot of fashion and advice videos, which he claims was his sisters and Tanya's influence. Then I believe once he established his friend group and started to do collabs, did he start to do the funny content that he mainly does now. He is also an amazing artist and has started to do drawing videos. Jim basically does it all. Oh and he attempts baking on his channel as well!
Jim has a lot of great things going for him right now. On top of his main channel (Jim Chapman), he has a daily vlog channel (EveryDayJim), he's currently preparing to run a marathon, he has been given presenter duties at big premiers, has his own column in GQ, and has his own stationary line!
He sure is a Jack of all trades and you'd be foolish to not check him out.
