Linus media group is expanding currently. They are making floatplane.
As for expanding and branching out it is a great idea but there is so much more to working then doing something you don't enjoy. The reason linus does what he does is because he enjoys technology, providing information to people and reviewing. He found a way to make money with youtube. Now making a retail business is providing a service he may not enjoy or has a passion about. That is why you see him expanding in the video/creators market because he has a passion to help creators have a better platform. I am highly certain he has little passion in sales.
