Black Mirror season 6 features many references and Easter eggs to previous episodes that expand its shared universe. There are many callbacks to iconic characters and events in Black Mirror's first two episodes alone, with several others hidden within the details of the remaining three episodes of the sixth season. With so much original content to reference, it's not surprising that the creators of Black Mirror packed season 6 with fun Easter eggs that expand the Black Mirror universe.

Introducing the Netflix-parodied Streamberry in Black Mirror season 6, episode 1 created a new platform that connects multiple Black Mirror installments. Black Mirror season 6's best and worst moments remain connected by thoughtfully placed Easter eggs and references to some of the most iconic Black Mirror episodes ever made. Many early Easter eggs came thanks to the Streamberry interface, but there were so many more in newspaper clippings, the musical score, and even recurring symbols.

15 Loch Henry Documentary Is Available On Streamberry

Episode 1, "Joan Is Awful"

"Joan Is Awful" opened season 6, with a woman named Joan learning that everything she does in life is being retold in a television show called Joan is Awful. This is on a streaming service called Streamberry (a spoof of Netflix) and she learned she gave up her life rights thanks to the and conditions. A virtual actor version of Salma Hayek plays Joan. Joan does humiliating things to sabotage the show, so Hayek sets out to destroy the quantum computers processing the show.

Since Streamberry is the service that shows the Joan is Awful show, there is a moment where the real Joan discovers this on the main screen. This also allowed several Easter eggs. A fictional documentary titled "Loch Henry: Truth Will Out" is on the Streamberry homepage. The reference is a rare moment of foreshadowing in the Black Mirror universe that hints at the next Black Mirror episode, "Loch Henry." The documentary is a narrative device in "Loch Henry" and is a central component in driving home the episode's message.

14 Finding Ritman On Streamberry References Bandersnatch

Episode 1, "Joan Is Awful"

Another fictional Streamberry documentary called "Finding Ritman" references Black Mirror: Bandersnatch and appears on the homepage in "Joan Is Awful." Colin Ritman (Will Poulter) is a central character in the uniquely interactive Black Mirror: Bandersnatch installment. Set up like a choose-your-own-adventure story, the episode featured several directions the story could go with five different endings. Ritman is a game designer, while Fionn Whitehead stars as a young programmer.

The fun part is that this proves that the game from Bandersnatch exists in the same world as Joan is Awful.

The fictional documentary seems to focus on the life and career of the mysterious game designer and might dive into what could have happened to him after the events of Bandersnatch. In Bandersnatch, Colin has two possible deaths (one where he asks to be bludgeoned with a trophy and in another, he jumps from a balcony, although this was a dream sequence). The fun part is that this proves that the game from Bandersnatch exists in the same world as Joan is Awful.

13 The Callow Years On Streamberry References The National Anthem

Episode 1, "Joan Is Awful"

"The Callow Years" is also another Streamberry documentary callback to a previous Black Mirror installment, season 1, episode 1, titled "The National Anthem." The fictional documentary seems to chronicle Michael Callow's term as the British Prime Minister. It would certainly cover the strange and tragic events that took place in Black Mirror's very first episode that likely marked Callow's career for life.

In The National Anthem, the fictional Prime Minister Michael Callow (Rory Kinnear) learns that someone has kidnapped Princess Susannah, Duchess of Beaumont (Lydia Wilson). He is told she will die unless he takes part in a live sex act with a pig, broadcast on national television. As much as he tries to keep from going through with this, he eventually gives in, only for his popularity to skyrocket after the event, although he was left traumatized. One wonders if that story plays out in this fake documentary.

12 Hot Shots & Botherguts! On Streamberry Reference Fifteen Million Merits

Episode 1, "Joan Is Awful"

"Hot Shots" and "Botherguts!" are both originally featured in Black Mirror season 1, episode 2, "Fifteen Million Merits." They can be briefly seen as viewing options on Streamberry's platform in "Joan Is Awful." "Hot Shots" is the equivalent to America's Got Talent in the Black Mirror universe where lower-class workers can audition to star in some type of show in order to attain a better life. Whoever wins in the competition gets to leave the impoverished lifestyle they live in for a more lavish one.

"Botherguts!" is a ridiculous slapstick comedy show that is featured throughout "Fifteen Million Merits." Unlike "Hot Shots," which is a huge part of the second episode storyline, "Botherguts!" is only seen for a few short seconds in "Fifteen Million Merits." However, the show's theme is obvious, as overweight people dressed in lower-caste yellow feast on donuts and cakes to win prizes while well-dressed people (the upper-caste) mock them.

11 Junipero Dreaming On Streamberry References San Junipero

Episode 1, "Joan Is Awful"

Another Streamberry content reference is called "Junipero Dreaming," which, based on the imagery and title, is a clear reference to the fan-favorite Black Mirror episode "San Junipero" (season 3, episode 4). Nothing is known about what the show actually is, but it likely either documents or romanticizes the dreamlike digital world portrayed in the classic Black Mirror episode.

"San Junipero" is an episode taking place in 1987 and following a party girl (Mackenzie Davis) who sees that her life is starting to defy the laws of space and time. However, the big twist here is that San Junipero is not real, and it is a place where elderly people can their consciousnesses into a VR system where they can live in this idealized world forever, and this episode is one of the rare ones with a "happy" ending for the two main female leads.

10 Joan Is Awful Newspaper References Grain Technology From The Entire History Of You

Episode 1, "Joan Is Awful"

A newspaper that is briefly seen in "Joan Is Awful" features a headline that reads "Grains Going Out Of Style." This is a reference to the Grain technology first seen in Black Mirror season 1, episode 3 "The Entire History of You." The Grain is the brain implant that allows people to replay memories in their minds as if they were video recordings. However, as the episode shows, constantly replaying past memories only causes trauma and distrust to ruin relationships,

The headline is an intriguing update of the imaginative technology, implying that fewer people in the Black Mirror universe are interested in getting them. With the way that "The Entire History of You" ends, and with Liam's final actions and the decision he came to, it is no wonder that the Grain implants didn't last very long when it came to customer satisfaction.

9 Stickers On David’s Laptop In Loch Henry Reference Multiple Black Mirror Episodes

Episode 2, "Loch Henry"

Several stickers on Davis's Laptop in Black Mirror season 6, episode 2, "Loch Henry," refer to previous episodes. In "Loch Henry," Davis and Pia are partners who are aspiring filmmakers and when they visit Davis's mother in his hometown of Loch Henry, Pia learns about a serial killer from the past named Iain Adair and she and Davis decide to make a documentary about him, only to find out that the case hits very close to home for Davis and his family.

Pia and Davis use laptops for research and video editing, and this allowed for several fun Easter eggs.

The blue Waldo logo references season 2, episode 3, "The Waldo Moment," which features a televised cartoon bear named Waldo. The black Tuckersoft logo below it references the fictional game developer in Bandersnatch. The eye sticker is a reference to season 4, episode 2, "Arkangel" and the infamous White Bear logo from season 2, episode 2, can be seen below it.

8 Space Fleet From USS Callister Is On Now Showing Poster In Beyond The Sea

Episode 3, "Beyond The Sea"

Black Mirror season 6, episode 3, "Beyond the Sea," features two astronauts in 1969 in space. However, this is an alternate world where technology exists that allows them to transfer their consciousness to replicas on Earth, where they can spend time with their families when they are not needed to work on the spaceship. However, after David's family is killed and his replica destroyed, he is trapped on the ship. His crewmate Cliff allows him to use his replica, but when David becomes obsessed with Cliff's wife, things grow out of control.

In a brief scene, a movie listing poster is visible in the background featuring "Space Fleet" showing in theaters. "Space Fleet" is the fictional Star Trek-inspired show introduced in season 4, episode 1, "USS Callister," "Space Fleet" was the television show that Robert Daly (Jesse Plemons) was obsessed with and based his space virtual reality game on. It is a great Easter egg considering both involve space travel.

7 Bloody White Bear Symbol In Beyond The Sea

Episode 3, "Beyond The Sea"

During the brutal scene in "Beyond the Sea" in which David witnesses his family being murdered, a quick shot shows one of the cultists wiping the walls in blood. It appears that the cultist was making the infamous White Bear symbol with the blood from David's family. This would make sense due to the cultists' disdain of advanced technology, and it could imply that they were trying to place the blame for the murders on the dystopian associations connected to the White Bear symbol.

This was an interesting Easter egg as it was more than just throwing in something from a previous episode for fans. This could be a way to show why David's family and his replica were murdered. With the astronaut using technology to spend time with his family, the killers could have targeted them for this exact reason, and with David's later actions, it would show why the cult was so dangerous, guilty of murders outside of even the ones they personally committed.

6 "Anyone Who Knows What Love Is" By Irma Thomas Recurring Song

Episode 1, "Joan Is Awful"

One song that originally appeared in "Fifteen Million Merits" continues to reappear throughout several Black Mirror episodes. "Anyone Who Knows What Love Is" by Irma Thomas has become a sort-of theme song across the Black Mirror universe, appearing in "White Christmas," "Men Against Fire," "Crocodile," "Rachel, Jack And Ashley Too," and most recently "Joan Is Awful." The song played when Joan was meeting Mac at the restaurant in the season six episode. "Anyone Who Knows What Love Is" has quite a history.

"If we can bring it back in and it adds to the overall sense of the universe or connection between some of the things that we’re talking about, then that’s great."

A young Randy Newman (a 22-time Oscar nominee for Best Original Score) co-wrote the song. When discussing why he chose to include it in Black Mirror, Charlie Brooker said, "It was originally selected for [‘Fifteen Million Merits’] because it was, it has the sound of a timeless haunting classic, yet wouldn’t be familiar to most viewers" (via The Wrap). Annabel Jones added, "If we can bring it back in and it adds to the overall sense of the universe or connection between some of the things that we’re talking about, then that’s great."
