On a ratings basis, the renewal of How I Met Your Mother was never in doubt, but whether the cast wanted to come back wasn't as certain. Deadline's Nikki Finke reports deals have been closed with all the cast members and the series will be renewed for a 9th season. The series had been in the final year of its deal and the creators had been pushing for everything to get resolved by the end of December so they could do the necessary build-up to the series finale reveal this season if necessary. Apparently all the cast were on-board to return except for Jason Segel: "But he just got turned around today at the last second. The show was literally dead,” according to Finke.
Updated: While the cast is now under contract for another season, the show has not been officially renewed.
