The BBC has announced the extension of the historical drama Call the Midwife for two more seasons.
The show will run until 2026 as a result of the announcement of seasons 14 and 15.
Beginning in 2012, Call the Midwife chronicles a group of East London midwives as they deal with issues like racism, domestic violence, and mental health issues in the 1950s and 1960s.
The drama will now take place in the 1970s, and its creator Heidi Thomas expressed her "overjoyment" at the renewal.
She added that the new show would examine the personal and professional lives of the nuns and midwives at Nonnatus House, the convent where they work.
Behind the scenes, on the screen, and in front of the television, we are a family, and I'm thrilled that we're all entering the 1970s at the same time, said Thomas. ".
Filming will begin in the spring for Series 13, which the BBC has already confirmed.
The 2022 Christmas special, which averaged 4.5 million viewers in overnight ratings, was followed on January 1 of this year by the return of the 12th season of the BBC One show.
After the King's Speech, the Christmas episode of Strictly Come Dancing, and Michael McIntyre's Christmas Wheel, it received the fourth-highest viewing audience on Christmas Day.
Each of the eight 60-minute episodes in series 14 and 15 will also have a Christmas special.
The program has featured a variety of celebrities over the years, including Miranda Hart, Helen George, and Jenny Agutter.
When the program first debuted, it was loosely based on Jennifer Worth's best-selling memoirs, which she wrote while working as a nurse and midwife.
The year before the debut season was broadcast, in 2011, she passed away.
The show's executive producer, Dame Pippa Harris, called its longevity a "tremendous achievement" and a "tribute to the passion and dedication of our cast and crew, of whom I'm very proud.".
On Sunday, February 26, at 8 p.m., BBC One and BBC iPlayer will broadcast the final episode of the current season.
