Continuity mistake: When the Spanish Language News Team arrives, the team consists of seven members. But once they all come down the stairs and get ready for the fight, there are six members.
Factual error: When Ron and the biker are talking on the bridge, a red cube van passes by in the background. Look closely: It's a 1990s model Ford Econoline, yet the movie takes place in the 1970s.
Character mistake: After Veronica Corningstone becomes an anchor, there is a montage of newspaper articles featuring her. Her name is misspelled as "Veronica Cornerstone" in one of the headlines.
Other mistake: In the article about Ron finishing 2nd in the hot dog contest, it says he's "now dubbed the Michael Jordan of wiener wolfing." Jordan didn't even start college until 1981. Not to mention Jordan was only playing JV high school basketball in 1978 in North Carolina.
Factual error: Although the film is set in the 1970's, when Brian Fantana is on the phone talking with a distraught Ron Burgundy, a Rubik's Cube is seen on the desk. Rubik's Cube was not sold until the early 1980's.
Suggested correction: First of, what it is isn't Rubik's original "Magic Cube" (later called Rubik's Cube). It's a 2x2x2 puzzle that looks like what Larry Nichols invented in 1968 and patent in 1972. The Rubik's Cube is 3x3x3.
