Way back when I first discovered Star Trek it became close to an addiction. It was akin to wanting to listen to a favourite song over and over and over again. I couldn't get enough of Star Trek and watched every episode whenever I could. Repeat and repeat again. 
That continued on into the late '70s where I began to taper off slightly as I got older and real life intervened. By the time TMP came around I wasn't able to watch Star Trek as often as I used to. And this routine continued on into the early '80s. I was still a diehard fan, but I had to balance things out with other things in my life and other interests.
But as my viewing fix tapered off I had begun getting into the second wave of original Star Trek novels from Pocket Books (the first wave being the original Star Trek books from Bantam Books in the '70s). The new novels served to feed my interest in new stories as an extension of the series' episodes. By the mid to late '80s I was probably reading the Trek novels more than watching the reruns on television. This also helped to get me through a decade where SF of the kind I liked was rather rare on television during the '80s.
The advent of TNG didn't help much. I wasn't impressed (for the most part) with TNG in the beginning and so it was something I only occasionally tuned into. I still much preferred watching TOS when I watched Star Trek. Oddly, though, I kind of enjoyed reading the early TNG novels as opposed to watching the show.
Watching SF on television and TOS in particular was being supplanted by reading books both Trek and non Trek SF. But during the early to mid '90s we began to get SF on television I did like (Babylon 5, Stargate, X-Files...) along with my occasional viewing of TOS reruns. When SPACE began broadcasting in Canada I began rewatching TOS a bit more often and catching up on some TNG episodes I hadn't seen before in daily syndication.
When TOS was remastered (the first time) I began watching the episodes more frequently again on SPACE and waited for the DVD season sets to be releases (the current clamshell sets I still have on my shelf). The DVD changed my watching TOS on television--I didn't bother anymore.
Presently when I watch TOS I usually run through the whole series from beginning to end in an entire series rewatch. Then I'll put it away for awhile and come back again several months to a year or so later.
And that's how it stands now. My next rewatch I plan on watching the series (with TAS mixed in) by order of Stardate. And now just for the hell of it I might include the STC episodes as well.
Anyone else?
