I added EEVblog2 for the extra "dump" content of random stuff, and that's been very popular.
Great idea it was IMHO.
For the rest I can summarize what follows as
separate channel is a good idea if: 1) it has content of a different style AND 2) it has a specific focus (say explaining basics, reviews...) AND 3) you are able to populate it frequently enough: once per week is a miniumum Then I added EEVdiscover because I had the plan to make more site visit videos (that's still on the cards BTW, Rode factory tour lined up). 20k people subbed to that.
I am not convinced it needed to be on a separate channel, but as long as it hosts not only electronics (such as voyager stuff) it is a fine idea to keep it separate. If you visit Intel HQ, then please make a redacted version for a main channel as well.
I thought about have EEVacademy but decided to trial having that content on the main channel.
To make it a separate channel, you would need much more content. Say once per week in a planned fashion. With the quantity you have now it is perfectly fine on the main channel. You have also playlists....
The problem with a "broad interest" channel like mine that does a large variety of content is that most people will see a lot of content that they didn't subscribe for.
Current system of putting a "keyword" such as EEVacademy, mailbag into the prominent place of the video title works just fine.
From my survey earlier this year only 32% said they watch every video regardless. So that's 68% of potentially unhappy subscribers with every video I upload.
There wasn't a single type of video that had over 60% of people agree that they enjoyed that content.
I skip some videos, but it does not make me unhappy.
1) should I split up content into more channels?
Only if you plan to substantially increase the quantity of the videos.
EEVreviews
This could be separate, but:
- currently your reviews are "spontaneous"/"first impressions" to some degree. It fits nicely with the main channel EEVBlog style.
- I see a place for more "extensive" reviews, akin to Linux Tech Tips style of electronic equipment - more prepared, more benchmarks, more systematic, more... but this would have to be separate, indepedent serious actvitiy, most likely requiring hiring new people. For example comparing signal generators, osciloscopes, multimeters of several brands. Quick justification: sub $50, sub $100 multimeters videos are out of date by how.
Actually it is similar to all channels: to make "more specialist" channels you need to have much more "specialist" content, which you will be unable to provide yourself. You need a larger team.
EEVblab (EEVrant/EEVopinion ?)
Are you able find a topic to blab about every week?
EEVacademy (EEVtutorial ?)
Yes, but only if you plan to make a systematic course in say "practical electronics" say "Soldering BGA's...", "Programming Mictrocontrollers", "Schmidt triggers for newbies" - this sort of videos.
EEVlive
Louis Rossmann has a shop and he can make live videos about his clients, projects, screwups, "right of repair" stuff. You don't have a company that deals with clients/politics every day. I am afraid that unless I am missing something, it will be difficult to fill this channel with content.
EEVvintage
EEVteardowns
these fit nicely on the main channel.
