After a promising debut for This Is Us, NBC has given the new drama an additional five episodes, taking the total number of instalments for the first season to 18. The decision was made on the eve of the show’s second episode.

Citing Live+5-day data, NBC said the show’s premiere attracted 14.3 million viewers. It also set records on NBC’s digital platform.

Commenting on the decision to extend the show from its initial 13-episode order, NBC’s Jennifer Salke said: “It’s a rare moment in this business when a show so instantly delivers both critical acclaim and hit ratings, but This Is Us is just such an achievement. Creator Dan Fogelman, along with co-directors Glenn Ficarra and John Requa and the producers, cast and crew, has delivered the kind of heart and depth that resonates with every segment of the audience and we’re proud to extend it.”

This Is Us is also making waves in the international market, with Channel 4 in the UK picking up the show last week. Jay Hunt, Channel 4’s chief creative officer, said: “This Is Us is unmissably life affirming with a warmth that has drawn critical acclaim and bumper ratings. It’s a great addition to our slate of acquired shows – from Deutschland 83 to Fargo.”

Fogelman’s other new series, Pitch, hasn’t had such a bright start, however. The story of the first-ever female Major League Baseball pitcher, the show was one of Fox’s weaker performers last week, bringing in 4.2 million viewers.

It has had a decent amount of critical approval, which means it will almost certainly complete its initial 13-episode run, but it will need to win over audiences quickly to secure an extended run or second season.

Among the other new US series to have hit the air, CBS reboot MacGyver has had a strong start, securing an audience of around 10.9 million for its first episode. This is the best performance by a Friday-night scripted series on the network since Hawaii Five-0 in 2014.

With the show’s debut clearly benefiting from in-built name awareness, it will be interesting to see if it manages to hold on to that number through episodes two and three. If it does, it means the revival is an inspired move. If it drops away quickly, it will resemble ABC’s experience with The Muppets last year – namely a strong start followed by rapid loss of audience interest.

The fate of MacGyver may have some influence on whether the big four US networks continue to look at reviving classic series. Others currently in the works are The Rockford Files and LA Law, and success for MacGyver will certainly mean more.

By contrast to MacGyver, ABC’s Notorious has started very badly and looks like a prime candidate for early cancellation. Fox’s reboot of The Exorcist, with 2.9 million viewers, has also started slowly but may find its niche in international distribution because of its name recognition and supernatural subject matter.

Still in the US, FX has revealed that season four of its vampire virus series The Strain will be the last. The Strain’s writer and showrunner  is Carlton Cuse, who is also coming to the end of A&E’s Bates Motel.

There had been talk of The Strain operating to a five-season story arc, but four seasons is probably enough to play the concept out. Strong in season one, the pace and direction of the narrative started to falter in season two – something that has been reflected in the ratings.

The downward path of the ratings tells the story. While season one averaged 2.2 million, season two came in at 1.34 million (this season also suffered from an awkward piece of recasting). Now in season three, the show is averaging 1.1 million but the latest episode attracted just 880,000 – the sign of a franchise coming to the end of its life.

Elsewhere, it has been a busy week for Australian drama. On the domestic front, Nine Network has commissioned a second season of Doctor Doctor, a local comedy drama about a formerly high-flying surgeon who is forced to work as a GP in the small country town where he grew up. The series, which sounds similar to DRG’s hit format Doc Martin, was only two episodes into the first season when Nine announced the recommission.

The show’s synopsis says: “When he is knocked off his pedestal and on to the Impaired Registrants Programme, prodigal Sydney surgeon and party boy Hugh Knight must return to his home in rural Whyhope where he might learn to swallow his pride and mend his ways – or not.”

Meanwhile, US-based SVoD platform Acorn has acquired two Australian series from distributor DCD Rights. The first is Deep Water, a four-part series inspired by a crime wave targeting gay people in Sydney’s coastal communities in the 1980s and 90s. The show is a Blackfella Films production for SBS Broadcasting Australia, Screen Australia and Screen New South Wales.

Acorn TV has also picked up the second season of political thriller The Code, which is produced by Playmaker Media for Australian public broadcaster ABC. Both series have also been acquired by BBC4 in the UK, a channel that is often used as a barometer of whether a show has international sales potential.

Finally, some desperately sad news this week with the untimely death of Gary Glasberg, executive producer/showrunner of NCIS and creator/executive producer of NCIS: New Orleans. Glasberg, just 50 years old, died suddenly in his sleep on September 28.

A well-liked figure, Glasberg joined NCIS in 2009 and helped confirm its status as one of the biggest drama hits in the world – a huge ratings success in the US and widely distributed internationally.

His previous credits included The Mentalist, Crossing Jordan and Bones.

“Today is an overwhelmingly sad day for NCIS, CBS and anyone who was blessed to spend time with Gary Glasberg,” said CBS president of entertainment Glenn Geller. “We have lost a cherished friend, gifted creative voice, respected leader and, most memorably, someone whose warmth and kindness was felt by all around him. Our heartfelt thoughts and sympathies go out to his wife, Mimi, his two sons and all his family and friends.”

CBS TV Studios president David Stapf added: “He brought kindness, integrity and class to everything he did. His remarkable talent as a writer and producer was only matched by his ability to connect with people.”
