Kayfabe Commentaries' YouTube channel (best of KC Vault) has released its "timeline" videos for 1992-2000. While each has WWF/WWE and WCW content, ECW was featured heavily for each year's video as well.
Here are the videos by year, including the name of the ECW veteran speaking on behalf of that year's timeline:
1992 - Tod Gordon
1993 - Tod Gordon
1994 - Shane Douglas
1995 - Sandman
1996 - Raven
1997 - Sabu
1998 - New Jack
1999 - Rob Van Dam
2000 - Justin Credible
At this time, there is no "ECW timeline" for the 3 shows run in January 2001 before the company stopped running events.
