Within a work, particularly long-running series and franchises, almost nothing changes. If something does change, it's generally reset back to the way it was before very quickly.
This usually happens in a series with no overarching conflict or plot, although it is also the final stage of Exponential Plot Delay, the phenomenon in which the plot of a serial story has totally ground to a halt. In either case, each installment of the series will open under virtually identical circumstances to the installment that came before.
Why create a static situation? The creators want the audience to be familiar with the characters and situation, without having to bother with such things as "what happened last episode". For example, they may use a title sequence that tells us everything we need to know, or, if the series has a serial plot, flashbacks, since Viewers Are Goldfish. Much like Failure Is the Only Option, any changes at all are resolved with a Snap Back or Reset Button. And God forbid anyone change the status quo of the surrounding world. Another reason is that some TV shows will have multiple episodes written and produced simultaneously, and it's easier to keep every episode ending the way it began so one writer doesn't inadvertently contradict another.
This trope is especially true for cartoons, where networks want to be free to broadcast reruns in any convenient order or lack thereof. It's also very common in sitcoms, and as a result, there are plenty of Broken Aesops created by the fact that, although characters have learned their lessons or attempted to improve their predicaments, nothing ever really changes.
While this trope can be used to help avoid Continuity Lockout — where a work becomes inaccessible to casual fans — it also be very difficult to juggle an unchanging status quo without gradually turning off your audience; characters and situations which never change tend to get stale after a while, and audiences can get a bit tired of seeing the Reset Button being pushed every time it looks like something might happen to change things.
Status Quo Is God can easily collide with Happily Ever After. Sometimes, a story simply can't have an ending that is both happy and maintains the status quo—thus, these two powerful tropes are in conflict with each other. When this conflict occurs, it's likely that the status quo will be maintained, and the ending will be less happy than it might have been if not for Status Quo Is God.
Negative Continuity is what happens when this trope is take Up to Eleven- not only does nothing ever change, it doesn't even require an explanation In-Universe, the world just resets at the end of every episode. See also, Alternate Universe Reed Richards Is Awesome, in which characters get a glimpse of an alternative universe where things have, in fact, changed.
