Revealing mistakes

Every one of Howard Beale's shows has the same studio audience (note the man in the black vest, with long hair and a beard).

Character error

Just after Beale announces his intention to commit suicide on the air, we see a row of TV screens showing how the story is being covered by the other channels. Playing a news anchor, John Gabriel claims that "something happened at one of our sister networks..." It should have been referred to as a "competitive" network - a "sister" implies the same corporate ownership, something prohibited by the FCC in 1976.

Factual errors

It is said early on that at one point, Beale's evening news program had as high as a 16 HUT rating. As HUT stands for Households Using Television, a HUT rating of 16 would mean only 16% of sets were in use, a low figure for that time of day where at least 60% would be expected. Additionally, the HUT rating applies to all programs airing at that hour. Individual program figures are reported as Household ratings or Household share. A rating is a percentage of all sets in the survey area, a share is a percentage of all sets in use at that hour.

Character error

Early in the film, after Howard Beale says that he's going to kill himself on-air, he's on the phone with Schumacher (Holden) angling to get his job back, and he mentions that he "has 11 years with this network." Later, following his on-air rant that "he ran out of BS," he's confronted by the press in the lobby of UBS where he says, "Every day, five days a week for 15 years, I've been sitting behind that desk..."

Continuity

Halfway through the first scene in Diana Christianson's office, the door, which had previously been open, is closed. Later, she walks over to the door and closes it again.

Factual errors

In 1976, the three major networks (ABC, CBS, NBC) sent out its network newscast live at 6:30 PM Eastern Time, and, barring any breaking news, aired them on tape delay at 7:00 PM Eastern, and thereafter. So unless UBS re-staged its newscast for each time zone, it would have been impractical for the network to have wall clocks on its news set.

Continuity

After attending a funeral service, William Holden And Faye Dunaway are talking on a street corner. Holden's hair is a little messy from the wind and passing traffic. A moment later, the two people cross the street and Holden's hair is back in place.

Anachronisms

The obituary for UBS Chairman of the Board Edward George Ruddy is shown with the character's information superimposed over the title area, with real January, 1975 obituaries for Revlon founder Charles Revson and screenwriter Sidney Buchman listed below. Additionally, the movie is set during fall 1975, months after Ruddy's death.

Factual errors

In the aftermath of Beale's assassination, one of the news outlets describes him as dying in a hail "of automatic rifle fire." However, neither of the assassins uses an automatic rifle.

Miscellaneous

The credits declare that Network was "filmed in Panavision" which is usually reserved for films in 2.35 to 1 scope. The credit was probably meant declare that the film was made with Panavision equipment.

Continuity

When Diana goes to Max's office to pitch her desire to program the news, the push-button telephone on the small lamp table just inside the office changes position from the start to the end of the scene.

Miscellaneous

Howard Beale is the lead segment of his eponymous show. No programmer as savvy as Diana would put the show's main draw as the opening segment, knowing that vast swaths of the audience would tune out after his segment, resulting in massive ratings drops after his appearance.

Factual errors

The (then) analog channel 3 was not assigned to Los Angeles. The nearest city where it was assigned, was Santa Barbara CA, some 90 miles away.

Audio/visual unsynchronised

After Howard's first on-air meltdown, as Max and the other network executives sample the reaction from other networks, they watch the other newscasts from a bank of three sets, each tuned to a different channel. As Max says he is not surprised each of the other networks is leading with the Beale story, he lowers the volume of each set in turn. The volume drops before Max's hand reaches the dials.

Continuity

In one scene Robert Duvall is speaking to a large group of stock holders. To Duvall's left, there are four seated men. The third man from Duvall sits with his hands under the table. A moment later, his left hand is upon his forehead.

Continuity

When Max tells his wife he's having an affair, the scene begins with him smoking a cigarette. A few shots later, he's still sitting in the chair but there's no longer a cigarette anywhere.

Continuity

During Howard's first stable rant (which ends with "turn your TVs off!") he walks right up to within inches of a TV camera just in front of the audience. It cuts to a shot from behind Howard, and the TV camera is now at least 6 feet away from him, almost not making it into the frame.
