I actually find the older episodes exciting to watch, especially since I really only got into soaps in the early-mid 2000s, but watched a bit of DAYS and GH in the 90s when my sister would watch. I know some people argue that the older episodes will not attract new viewers, which is probably true especially since they're not running week long edited storylines, but instead theme weeks around characters so there's not much connection, continuity or conclusion for new viewers to really get into. But I don't think soaps in their current state would attract much new viewers. I think the hope (if even possible) is to lure back some of the viewers they've lost recently. I by no means am a YR fan, although the CBS soaps (B&B, GL and ATWT) have been my favorites to watch and I watched them pretty regularly between 2003-06 and on and off since then. I actually found myself enjoying these one off Y&R episodes. They really show how great soap operas really were...the masquerade even as a one off was exciting for me to watch even though I knew nothing of what had occurred leading up to those events, but I guess knowing the characters helps.
I think instead of theme weeks surrounding characters, Y&R should consider theme weeks around popular storylines. They can air 5 of the more exciting episodes of a particular storyline over the course of the week with actors providing commentary at the beginning and even halfway point to fill in viewers. I know this is probably time consuming and not worth the effort from CBS, but it would be exciting for me. These old episodes finally made me understand why YR has been #1 all these years. Honestly, when I started watching soaps I always wondered why YR was ranked so high, aside from its production value in comparison to some of the soaps, I didn't find it that interesting a lot of the time. Now I get it and I definitely see that it was holding onto viewers from its past.
