As per the title, I am after a well presented look at major events from the 20th century. They don't need to be massively in-depth but provide a good overview with the key points e.g.:
Civil Rights Movement Space race Cold war
Ideally the videos would be relatively short (less than 10 minutes).
Any recommendations?
Finally something I can actually be useful for in this sub!
For what you've asked (and more) you can check out CrashCourse's sub: https://www.youtube.com/user/crashcourse/playlists
Their videos are usually around the 10min mark, with plenty of citations, research and related material being discussed, addressed and/or linked.
I'm quite partial to the lectures put on YouTube by the National World War I Museum and Memorial in Kansas City. https://www.youtube.com/user/NationalWWIMuseum
While it may not be exactly what you wanted, The Great War follows the events of WWI week by week, along with other interesting episodes.
