I'm starting a new series on YT and I have an older channel that is kind of related to the same content. The older channel only has a few hundred subscribers but most of them seem to be inactive. I'm wondering if I should start a new channel for this new series. I'm mainly concerned about branding and I'm worried about the new series being lost in the mix of all the other stuff on the old channel. This series is also for a more targeted niche. It's for kids. The old channel is for the business which is for kids and families but marketed to mainly adults. . Should I start a brand new channel?
