The entire concept revolves around this, with each universe having its own Spider-Person. Indeed, Miles' own universe has quite a few differences from our own.
- The various Bland Name Products are demonstrated outright to be alternate universe equivalents to real brands. For example, a "Koca-Soda" ad in Miles' world is an actual Coca-Cola ad in Peter B.'s universe.
- Similarly, near the end of the film, we see that Spider-Ham's universe has Porka-Cola.
- New York City's police department is given the acronym PDNY (Police Department of New York) instead of NYPD (New York Police Department). Conversely, the real-life FDNY (Fire Department of the City of New York) is instead called the NYFD (New York Fire Department).
- Police vehicles aren't exempt from wearing registration plates, as seen on Miles' dad's police cruiser.
- The lights on police cruisers flash in red and blue instead of red and white.
- Snapchat is still called Picaboo, and Google is still called Backrub.
- The Blue Man Group is called the Red Man Group.
- T-Mobile is instead C-Mobile.
- A poster in Miles' dorm room shows Chance the Rapper
wearing a cap with the number "4" on it, instead of his signature "3". - An ad shows The Weeknd's "Starboy" cover design, but with his old persona's haircut.
- Taxicabs use the "NYC Taxi" livery design introduced in 2007 instead of the current black circle with a negative-space "T". In addition, taxis and police cars are made to resemble the older second-generation Ford Crown Victoria, an increasingly rare sight as both since the model's discontinuation in 2011, but still a popular prop in film and television for its surplus availability.
- The current black-and-yellow "Empire Gold" license plate design issued since 2010 and the previous white-and-blue "Empire State" issued from 2001 to 2010 are used simultaneously on some cars, also as seen on Miles' dad's police cruiser.
- New York is shown to be much larger in Miles' universe. In the first scene of the teaser trailer, much of the Manhattan skyline is taller than the Empire State Building, currently the fourth tallest building in New York. Some of these skyscrapers are lit with projected advertisements.
- Miles doesn't know what Comic-Con is, suggesting it either doesn't exist in his world or it has a different name.
- Zastava Automobiles' "Yugo" line of hatchback cars was a success in both Miles' and Peter B's universe, with modern models advertised alongside the slogan: "Wherever Yugo, I go. It'll get you from A to B".
- Golden State Warriors basketball legend Stephen Curry is instead a golf pro in Miles' universe, with a billboard touting him as "The Golden Boy" of the sport. (Truth in Television, as Curry is an avid and talented golfer in the off-season.)
- A Times Square billboard shows that NBA star Blake Griffin is instead an MLB player in Miles' universe (again, Truth in Television, as Griffin also played baseball before choosing to focus on basketball). The team he plays for is the New York Red Sox; in Real Life, that's Boston's team name, a nod to the notorious Red Sox/Yankees fanbase rivalry.
- Pop culture as Miles knows it is very, very different; on Spider-Man's arrival alone, we see advertisements for a horse-racing comedy starring Seth Rogen called Hold Your Horses, John Mulaney and Nick Kroll star in Hi, Hello instead of Oh, Hello, the proposed Shaun of the Dead sequel From Dusk Til Shaun was actually produced, there's a Clone High movie, and Bridesmaids has a sequel titled "Baby Showers".
- Doctor Octopus is a woman in Miles' universe, here named Olivia Octavius.
- The approval stamps on Miles' "True Life Tales of Spider-Man" comics are from the "Cabin Fever Production Code" rather than the Comics Code Authority.
- The Planet Hollywood restaurant and resort chain is called "Planet Inglewood." This also implies that in Miles' universe, Inglewood is the heart of the American film industry.
- One of the posters you can see in the background is for EA Sports' latest Water Polo game. EA Sports is a real publisher (best known for the likes of FIFA and NBA licensed sports games), but they don't (at the time of writing) make a water polo game.
