If you're a media history buff like me, and you have a special interest in TVB's forty-two year long history, have I got a resource for you:
This Tudou page, by an anonymous author, compiles a listing (complete with original Hong Kong broadcast schedules) for *every* series that TVB broadcast from the first day the station went on the air in 1967 through September 13, 2004 (although for some reason, the history ends abruptly on that date).
This is the only listing that I've seen of this type for TVB. I found that it's missing a few series, but overall, it's the most exhaustive log of TVB's broadcast schedules over four decades that I've ever seen.
For me, it answered the long-standing question of what TVB's very first dramatic series was. As it turns out, the series was named UNDER MT. TAI PING. The webpage offers no information on who performed in this drama, who the production staff included, and what the series was about, but at least I now know the title of TVB's first series.
