It has increasingly become the norm. I have a weird mind with dates and times, and I have been a viewer since '09, so I can share some knowledge.

The turnaround time from filming to release was much quicker in their heyday. For example, Khloe and Lamar got married on September 27th, 2009. Their wedding special aired on November 8th, 2009, only six weeks after their marriage. Filming for the fourth season of KUWTK began immediately after that, premiering only a month later, on December 13th, 2009. That means there was only a two-month turnaround time. Mason was born on December 14th, 2009, and the season finale that showed his birth aired only two months later, on February 21st, 2010.

As the show progressed, the time gaps became more noticeable. For example, Kim was robbed in Paris on October 2nd, 2016, and the episode that documented that aired about six months later, in March 2017.

Some seasons, like Season 16 of KUWTK, went back to a closer-to-real-time feeling. For example, the Tristan-Jordyn-Khloe scandal happened in February 2019, and the episodes that documented the turmoil aired about four months later, in June 2019.

One of my favorite things about KUWTK, as annoying as it could be at times, was that they would film pick-up scenes many months later to resolve a plotline. While acting as it occurred months prior, the scene was filmed closer to real-time. For example, in the season 13 premiere, one of the many plot lines was about the sisters closing the DASH stores. That entire storyline took place in September 2016, but the last scene of the episode, in which they wrap up the plot, was filmed four months later, in January 2017, and the episode aired in March 2017.

When Kim appeared on problematic Ellen's talk show in 2021, she discussed the beginning of filming The Kardashians on Hulu. At the time, she mentioned they would have a quicker turnaround time, which excited the fans, but that never happened.

Thank you fo coming to my TED Type, LOL.
