I found the site about a year ago when I found retrojunk. Of course, this one was easy. The other I found out of sheer luck and sitting at the computer until 4am.
It was actually an European site but it had bumpers dating back to the first ones shown for ABC, NBC, CBS and even those ridiculously long teaser bumpers when FOX was just coming on air in, what, '87?
The site in question also had HBO, Showtime, Cinemax, etc. Like many typical Euro sites, it unfortunately had a thing for real player. I'm going to keep looking but I need Y'alls help!
