Steven has always wanted to attend CES and wants to know if he could get in if he started a blog. Leo says that CES does allow "qualified press" into the conference, and attendees have to prove it. Here's CES official media requirements - https://www.ces.tech/Logistics/Registration-Information.aspx
But Bloggers, YouTubers and "popular influencers" do get in. But Steven would have to have some influence and reach with a site that has consistent numbers and content. So get started now. The other option is to get to know someone who has a booth there and then ask them for a pass.
