There are a lot of different sites that you can watch Glee on for free. I will keep a running list in this post and if any one runs across somewhere I missed please add a comment with the info and your experience watching it there.
Hulu Has the current episodes and I have watched here with no probs.
Fox also shows them but they want you they want you to install their player which I refuse to do. I don’t trust Murdock.
You wouldn’t believe the amount of spam scammers wanting to get a link on this post. I removed one link I had within the post because it was a scam.
But if you are in the UK here is a new one for you:
Channel 4 has Glee!
