Indigo Gaming's YouTube channel shows "Insightful game analysis, reviews and retrospectives with an emphasis on historical importance and their impact on the industry. No politics..."

For an example with its long Cyberpunk Documentary in parts: #1 (47 minutes and 47 seconds), #2 (almost 1.5 hours), and #3 (underway) -- "Let’s take a journey back to the 1980’s and beyond, to discover the origins of the Cyberpunk movement, in literature, cinema, television, video games, comics and more! In this documentary miniseries, we will discover the wonders of Cyberpunk, dating back to the 1940’s, all the way through 1989, with each successive episode taking on a new decade...

They show many medias like books, (movie/f(ilm/lick))s, tel(evision/ly)/TV, video games, etc. with spoilers.

Lessons from the Screenplay's YouTube video channel -- I believe that a more informed audience raises the bar for storytelling. That examining the techniques used to tell great stories makes your own writing better and your appreciation for the stories deeper. With Lessons from the Screenplay, I make videos that analyze movie scripts to examine exactly how and why they are so good at telling their stories. Part educational series and part love letter to awesome films, Lessons from the Screenplay aims to be a fun way to learn more about your favorite films and help us all become better storytellers. I’ll be releasing new videos every couple weeks, and taking suggestions about what scripts I should look at in future episodes.

Also, its 59 seconds YouTube video mentioned its new YouTube spinoff channel -- "Story Mode is a video series from the team behind Lessons from the Screenplay dedicated to exploring storytelling in video games.

LeagleEagle's YouTube channel shows many interesting videos of discussions about T(el(evision/ly)V and f(ilm/lick)s -- "... Do you want to know how our legal system works? You’ve come to the right place. LegalEagle is all about giving you an insider’s view to the legal system. Have some fun and learn to think like a lawyer.

I get asked a lot about whether being a practicing attorney is like being a lawyer on TV. I love watching legal movies and courtroom dramas. It's one of the reasons I decided to become a lawyer. But sometimes they make me want to pull my hair out because they are ridiculous. So I created this channel to answer your burning questions about the law and the legal profession. While all legal movies and shows take dramatic license to make things more interesting (nobody wants to see hundreds of hours of brief writing), many of them have a grain of truth. Learn everything you always wanted to know about being an attorney! ..."

WTMRecut's YouTube channel has several parodied videos from movie/f(lick/ilm)s and tel(evision/lly)/TV s(erie/how)s. They can be amusing too.
