I haven't posted here mostly because there are currently 528 "public channels" on Roku and maybe over a thousand "private channels." Some of the free public channels certainly have limited appeal such as Beautiful Homes of Los Angeles. You can access the lists through a site called RokuGuide.com. It's possible that 10% of the public channels might be interesting if I took the time to sort through them all, but I haven't. There are certainly many free or ad-supported channels to peruse.
