It’s funny that unedited, poorly rehearsed “presenting style” has in a way taken on a life of its own. Speaking to a director off-camera, quick jump cuts of multiple takes, drawing attention to flubbing of lines, are all sort of techniques used in YouTube videos to show “authenticity” to the viewer (ie, I’m just a regular person making these videos).

I was listening to a podcast recently and noticed they left in some banter before an interview started. The banter added nothing to the discussion since they weren’t even talking about the topic yet. Its sole purpose was to make the chat feel informal and, in my opinion, “more real”.

Meanwhile radio shows were taking out individual ums and errs, even in the analog era.

This. Although I have discovered why the jump cut is so popular! Actually, even inexpert jump-cutting does improve things though, so worth doing.

Extensive use of jump-cuts lets you edit single-camera monologues as if they were text. Much easier & cheaper than doing re-shoots, using multiple cameras, et c.

I can personally attest that this style was extremely off-putting to us oldsters (millennial here—yeah, we're getting old) until we'd had a few years to get used to it. It's not something you see in traditional video media unless a mistake happens, or you're watching some kind of weird art thing.
