Thinking about this, I remember that most shows when I was growing up didn't show episode titles. Star Trek did, The Wild Wild West did, Batman (I think) and a few others, but I'm pretty sure that those were the less common examples.Seems more and more shows don't show their episode titles anymore. I don't know if its a "prestige" thing or whatever, but I generally like to know the title of the episode I'm watching.

Do you like it when a show starts their episode with the episode title revealed, or do you just not care?

I think I'd be annoyed if a show I knew displayed titles suddenly stopped doing so without explanation, or if the network affiliate edited it out for broadcast, but if they don't put the title on the film/tape in the first place, eh, it's not going to cause me to lose any sleep.
