(written from a Production point of view)
G4 was a male-oriented television network (formerly video game-oriented) which started airing Star Trek: The Next Generation in January 2006 and Star Trek: The Original Series in April 2006 as Star Trek 2.0.
It only airs The Next Generation after 8:00pm EST due to Spike having the rights to air it in the morning and afternoon. The Original Series also aired (until November 2006) in "Uncut Marathons" on Saturdays which are in fact the original NBC versions of the classic episodes before the cuts were made for the syndication package.
