Have also heard about AmazonFree but not looked into it.
You can watch some shows on Amazon for free, with commercials. I have a Roku with the Amazon Prime app installed, but I don't have Amazon Prime. It lets me watch whatever is designated as free. I figured this out when I was researching which streaming service had a show I wanted to rewatch, and it turns out it's on Prime for free! I hate commercials, but hate Prime more, so it hasn't been hard to sit through them.
Paramount+ keeps putting out free month codes, so I haven't paid for that, either.
Also a reminder to check your local library! They have tons of TV series you can check out.
When I moved to my new apartment after my summer seasonal job ended a few weeks ago, I assumed I would pay for one streaming service at a time, and just rotate through them to watch the shows I wanted to watch. But after wandering through my library after attending a bookclub meeting, I was reminded that they have DVDs! Duh! I might still end up subscribing to a service eventually to watch a hot new show, but it doesn't need to be a constant expense for me.
You become a lot more productive and also develop real hobbies.
Meh. I watch TV while doing some of my "real" hobbies (like cooking and knitting). But I do agree that it can be a time suck, and really enjoy my TV-free summers (but those are also cooking- and knitting-free summers).
I'm currently unintentionally plowing through seasons of shows because I'm in a charity knitting group, and just got some new donated yarn to work with, so I'm really addicted to knitting at the moment.
