A video telephone was an invention that allowed someone to view the other person on a television screen while talking. AT&T marketed some video telephones by 2015, as well as providing video payphones like the one present in Courthouse Square.
On October 21, 2015, Marty McFly received video telephone calls from Douglas J. Needles, and Ito T. Fujitsu. In both cases, during the call, a datafile of the caller appeared at the bottom of the screen below the video image, which listed below the caller's name (in order of appearance): 'Occupation', 'Age', 'Birthday', 'Address', 'Wife', 'Children', 'Food Preference', 'Food Dislike', 'Drinks', 'Hobbies', 'Sports' and 'Politics'.
When Mr. Fujitsu fired (or "terminated") Marty by fax, the content — "YOU'RE FIRED!!!" — was superimposed over the video image in large upper-case letters that filled the screen, and at the same time it was sent to and printed out by all the fax machines in the McFly residence. A copy of one of these faxes was taken by Jennifer Parker, who was hiding in the house at the time. (timeline in which Marty has 1985 car accident )
Marlene McFly was able to talk on the video telephone using her video glasses, which displayed the orange illuminated word PHONE across the front as she did so. However, Marlene had to interrupt her conversation when Needles called, as the McFlys only had one phone line.
- In real life, video telephones have existed since 1936 in Germany and since the 1960s in the U.S., but were never popular because of the slow bandwidth of telephone cable and a lack of public demand. With the development of DSL and cable networks, personal and corporate videoconferencing services such as FaceTime and Skype are now available on home computers and cell phones. Skype can also be used with a television set, with the addition of a webcam that is compatible with it.  However, unlike the AT&T video telephone seen in Back to the Future Part II, callers' datafiles do not appear on-screen. FaceTime can only be used with iPads, iPad Touches and Mac computers .
- AT&T developed a Picturephone service in 1970, but it attracted very few home subscribers.
