I saw the very first episode! It was the summer of '66, and I was watching some game show on the ABC affiliate, 10:30 in the morning. Why I was doing that rather than playing outside is beyond me. Anyway, at the end, they had that commercial and I thought it looked fascinating, the new show coming on next at eleven. Obviously, it was a delayed broadcast since it came on in the morning. From that point on, I watched it on and off, only partially interested because it wasn't really "scary" yet, but I clearly remember the story of David trying to kill his old man and all that. I and my friends even played our own version of it (hiding one of those old hotel key chains that read drop in the nearest mailbox in place of the brake thingamajobby. My interest remained pretty much partial during the rest of the first storyline, as well as the Laura plot, and really picked up during the Barnabas fracas. By that time, Dark Shadows had moved to its mid-afternoon time slot. From that moment on, I was hooked.
There were battles with my mom, who didn't want me watching "such crap", plus it came on opposite Art Linkletter's House Party, a show which many 60's housewives viewed as sacred as Lawrence Welk. However, I won that war, and Art was eventually canceled anyway. Plus, whenever Joan Bennett appeared, my mom would sit for a few minutes to watch her on "that crap".
