There's a huge difference between anthologies and episodic shows.
Obviously there is. I'm merely pointing out that people in the past favored episodic shows because of the prestige of anthologies. The ideal was to make a show that had the audience appeal of continuing characters (and the budgetary appeal of standing sets and reused props and costumes) but still had the flavor of an anthology. Plenty of '60s series were like this. Star Trek was designed to be a semi-anthology, with the characters visiting a different world and getting embroiled in a different SF situation each week, and interacting with guest stars who could grow, change, or die in the course of a single hour. The Fugitive used Richard Kimble's wanderings largely as an excuse to get him involved in the drama of a different cast of characters each week; the stories were really more about them than about him. The same went for many of the shows that emulated its formula, such as The Incredible Hulk. Many episodic shows back then were "stealth anthologies," just as a number of episodic shows today (such as House and Fringe) are "stealth serials," slipping larger arcs into their case-of-the-week formats.
Let me clarify: I'm not arguing this opinion on my own behalf. I'm merely pointing out that different generations have had different preferences. The only opinion I'm asserting is that opinions come and go and we should have a healthy sense of perspective about our own preferences.
What people decided to do in the past is neither here nor there.
Except to remind us that we will be "people in the past" before too long. This, too, shall pass.
