Help me out!

Hi, there?
I love to watch the TV show Friends and Oprah show.
Can I watch the shows on the internet?
In South Korea the stations have their web sites and we can watch the previous shows on the internet. It’s called VODservice in Korea. I tried to find that kind of service to watch the shows, Friends and Oprah Show, but I couldn’t.
Pleas let me know where I can watch those shows on the internet.

Have a great day!!
