Check out Link TV
www.linktv.org

What? You say you have never heard of it? Drop Comcast like a bad habit and boycott them for life. I did.
Where Comcast drives out competition and raises rates, they also don't put LinkTV on their what 900 channels. Maybe there is a reason they don't want you watching Link TV.

Drop Comcast tomorrow. Get Direct TV or Dish Network (I believe they both carry it). But check it out first. I have Direct TV and they have Link TV on 375 where I live.

There is some pretty interesting stuff they put on there. A glimpse at cultures around the world. Interesting music. Politics.

They have aired The Corporation. Harry Belafonte (never knew he was such a powerful speaker!!), Amy Goodman / Democracy Now and a lot of other cool content that is outside the mainstream media.

Then go back and ask yourself again, why would Comcast not show Link TV? Apparently they are "considering" Link TV but haven't put them on the air. So drop them now.
