What was this about? KeepMyTv.org?

An advertisement for this movement popped up on my local news Internet site. Was there some pressure in the past from cable and satellite companies lobbying the US congress to halt free OTA TV? I tried to find out more, but came up with nothing. It appears to be over with now, but I never heard about this.  

Edit: I see that there is already a topic on this......sorry.
