There were, at different times, two companies that did that.  Both went
under because expenses exceeded income.

The one that was _much_ more interesting was the one that Lauren Weinstein
had a hand in.  It piggy-backed a Usenet feed in the vertical blanking
interval of several big "independant" TV stations -- ones that were 
carried by practically every cable company in the country.  Distribution
to the cable companies was via satellite, but the USENET feed, being 
_part_ of the video signal, consumed _zero_ additional bandwidth, and
rode the satellite links for free. 

To get the feed, all you needed was a TV tuner with 'video out', and the
purpose-huilt decoder box that extracted the vertical interval data.

This service died as the independants moved to encrypted transmission,
because the encryption did _not_ perserve anything in the 'blanking'
timeslot. only the 'viewable' field-image was trasmitted, _as_ a full-field
image.  Sync, blanking, etc. was _locally_ generated on the receiving end.

An "elegant" idea, done in by changing technology.   *sigh*
