SorryHow I Met Your Motherfans, but if you were looking forward to the in-the-works spin-off, you are going to have to wait. Maybe for a long time.This is UswritersIsaac AptakerandElizabeth Bergewere the ones working on the show, which is currently titledHow I Met Your Father. But now thanks to a promotion, they are going to be far too busy to work on the show right now.

The good news forIsaac AptakerandElizabeth Bergeis thatThis is Ushas been a tremendous success on NBC and the network decided to give them a larger role in season 2.The Hollywood Reporterbroke the news that NBC will be making them co-showrunners alongside creatorDan FogelmanonThis is Usseason 2. While that is good for them and probably good news for fans of that show, it is definitely a bummer for those who wanted to see some theHow I Met Your Mother spin-offmake it to air.

“Isaac and Elizabeth are incredible talents who write with such passion and emotion; their voices are bold and original and the contribution they’ve made to This Is Us this year has been extraordinary. They are hugely valuable to Dan and to everyone at this studio, and we are thrilled that they will showrun alongside him next season as well as remain in the studio family for years to come.”

20th TV president of creative affairsJonnie Davishad that to say about the writing duo in a statement following their promotion. There is a possible silver lining here. At the moment,How I Met Your Fatheris not attached to a network, even though the original series aired on CBS. It is possible that NBC could decide to pick up the spin-off as their relationship withIsaac AptakerandElizabeth Bergeblossoms since they seem to really enjoy working with them. In the long run that could present a good creative relationship and a better possibility for the show to actually make it to air. That is purely speculative and it certainly doesn’t change the fact that the show has been shelved for the time being.

This is not the first time aHow I Met Your Motherspin-off has encountered adversity. CBS hadshot a pilotfor a spin-off titledHow I Met Your Dadthat starredGreta Gerwigas Sally, a young New York woman who is on the verge of divorce after being married for a year, finding comfort from her friends and family.Meg Ryanalso signed on to narrate the show as the “future Sally,” much likeBob Sagetdid in the original series as “Future Ted.” None of the original characters starred in that pilot, but it did feature the MacLaren’s Pub hangout fromHow I Met Your Mother.

CBS had a ton of success withHow I Met Your Mother. The show ran for 9 seasons with a total of 208 episodes and delivered ratings for the network. So it makes sense that aspin-offhas been looked at, but actually getting it off the ground has proved to be quite difficult. How I Met Your Father may not be dead, but this new development certainly will delay things.
