I'm not giving up... not yet. But I am not going to continue to prioritizing new videos. I will make them when appropriate and am tinkering/exploring with moving the entire channel to DailyMotion instead, which seems to have a more favorable monetization program: https://www.dailymotion.com/dm_33b3957010574f55b19df32c79a11eb9
As far as YouTube is concerned, look at how the increased number of videos has inexplicably resulted in a lower baseline of views:
Digging deeper into the analytics, it seems like the more content I create, the less referrals we get from search results and recommended videos. YouTube is ranking the videos lower in the results and/or not displaying them at all. Sooo...... I'm going to leave the channel to coast a little and see if the baseline drifts back up with LESS activity.
I'm also exploring combining the channels I have onto one account in addition to the DailyMotion option.
