Before I reply to some of the posts in this thread, something I recall to mind that I hadn't thought about for a long time and need some verification on this...
Long before the Ch9 2 Friday night games/round format began in 2007, I remember back in 1998 (round 4) as a one-off, Ch9 televised 2 Friday night games into NSW that night:

IIRC, Manly vs Parramatta was televised at 8:30pm (1hr delay) followed by the replay of Melbourne vs Norths at 10:30pm. Storm vs Norths was live on Fox at 7:30pm, but Ch9 replayed the Fox broadcast/commentary 3hrs later. It struck me as odd that Ch9 did a Friday night double header that round. The only reason I can think of why this happened is because it was the Storm's first home game (infront of a jam-packed Olympic Park of 20k). Some highlights from that game can be seen in this Marcus Bai try compilation video, and you will notice the Ch9 logo in the top right despite using the Fox on-screen graphics and commentary:
It's interesting to note back then, the live Fox match went head-to-head with Ch9's 8:30pm Friday night game; something that would never happen today, as the NRL has this obsession with not wanting to schedule matches that kick-off at the same time or overlap.
I remember reading in the newspapers at the time that Melbourne vs Norths game rated very well on Ch9 despite the late 10:30pm timeslot. Back in 1995/96/98 when the comp was 20 teams, 2-3 Friday night games/round were common but only one was televised into Sydney.
In Rd 9 1998, there were a staggering FOUR Friday night games - the most since Friday night games began back in the '80s:
