The familiar 20th Century Fox production company logo is shown at the very end of the show, but has been modified to read "30th Century Fox", since the sci-fi series begins in the 30th century. Note however that in the first episode it is a minute before New Year's Eve of the new millennium, and the rest of the episode and the entire series takes place in the 31st century. This is somewhat of an industry joke, since the production company debated for a long time what to do when the year 2000 came around: would they change their name to "21st Century Fox"? Futurama began its first season in 1999, with the pilot's story beginning on December 31, 1999, just before the big decision at 20th Century Fox had to be made. The decision of course, was to drop the century altogether and call the company simply "Fox".
Though the cartoons shown on the giant monitor are usually old, vintage cartoons (most likely public domain), on at least one instance a clip from a Simpsons short (from the Tracey Ullman Show) was used (Matt Groening created both Futurama and The Simpsons).
During the opening, old 1930s cartoons are played on a giant monitor and are different each time. In the episode "Roswell That Ends Well", the cartoon featured in the opening was played in the episode on a small TV. Also when the title appears, a new message appears every time.
Occasionally, before the opening credit sequence begins, the show will be "sponsored" by a futuristic sponsor advertisement. For example, "Futurama is brought to you by Glagnar's Human Rinds." The show always begins with a parody of the "Transmitted in SAP" type of show disclaimers when the title "Futurama" appears. For example, "As Seen on TV" or "Present in BC (Brain Control) Where Available".
In syndication, the 30th Century Fox logo made for the show is typically followed by a regular "20th Century Fox Television" logo.
Many episodes have guest celebrities doing voices to depictions of themselves (usually just their heads in jars). Occasionally, a few famous people who appear are not voiced by the actual celebrities, but by the regular voice crew (with the notable exception of Rich Little). However, at the end of every episode, the typical disclaimer is given, with an addendum. The full text reads: "The persons in this film are fictitious. Any similarity to actual persons or events is unintentional. Certain celebrity voices have been impersonated." This disclaimer is mostly inaccurate, as real actual persons (named in the show) and historical events ARE intentionally depicted (in a fictional setting of course), and most celebrity voices portraying themselves are in fact the real celebrities.
