Light from the performer passes through the front side of the glass into the lens, while a shroud surrounding the lens and the back side of the glass prevents unwanted light from entering the lens.

illusion from classic theatre: an image viewable from one angle but not another. Because the speaker can look straight at the lens while reading the script, the teleprompter creates the illusion that the speaker has memorized the speech or is speaking spontaneously, looking directly into the camera lens. Notes or cue cards, on the other hand, require the presenter to look at them instead of at the lens, which can cause the speaker to appear distracted, depending on the degree of deflection from the natural

who suggested the concept of the teleprompter as a means of assisting television performers who had to memorize large amounts of material in a short time. Schlafly built the first teleprompter in 1950. It was simply a mechanical device, operated by a hidden technician, located near the camera. The script, in inch-high letters, was printed by a special electric typewriter on a paper scroll, which was advanced as the performer read, and the machines rented for the then-considerable sum of $30 per hour. The teleprompter was used for the first time on December 4, 1950, in filming the CBS soap ''The First Hundred Years''. It was used by

Presidential (or glass) teleprompters

Glass teleprompters were first used at the
1956 Democratic National Convention The 1956 Democratic National Convention nominated former Governor Adlai Stevenson II, Adlai Stevenson of Illinois for president and United States Senate, Senator Estes Kefauver of Tennessee for vice president. It was held in the Internation ...
. The inventor of the teleprompter, Hubert Schlafly, explained that he wanted to create a less obtrusive teleprompting system than the ones used at the time. He said, "We developed a 'one-way mirror' device we called the ''Speech View'' system... The prompter, hidden in the base, reflected the text on the glass to the speaker while the audience looked through the glass without being aware of the text. Two such prompters, one on the right and one on the left of the speaker allowed him to switch from one to the other and appear to address the entire audience".Laurie Brown, ''The Teleprompter Manual'' (Pleasant Ridge, Michigan: The Difference Press, 2006), pp. 5–6. . Schlafly's company then created a speaker's lectern that included two synchronized glass teleprompters and a range of technological innovations including air conditioning and an adjustable-height speaker's platform. The success of the system led the company to develop a new model for use on TV cameras, with the glass placed directly in front of the lens. The camera "looked through the glass; the performer looked directly at the TV audience and was able to read the text word for word. This device now has worldwide use". Typically, a screen on either side of the speaker shows mirrored text from upward-facing floor monitors at the base of a stand supporting a

, Illinois, used a four-teleprompter system: as can be seen at another convention in image (A), the first three prompters are placed to the left, right and in front of the speaker, the latter embedded within the speaker's lectern, enabling the speaker to look down at the lectern without losing their place in the text of the speech; while in image (B), the fourth prompter is a large confidence monitor located immediately below the lenses of the TV broadcast cameras, at a distance of several meters/yards from the speaker. This modification to the traditional two-teleprompter set-up continues to be in use at both the Democratic and Republican parties' national conventions: the two glass teleprompters on either side of the speaker's lectern create the illusion that the speaker is looking directly at the audience in the hall, the monitor embedded in the lectern, together with the fourth, much larger teleprompter screen, known as a "confidence monitor", placed immediately below the broadcast TV cameras which are located some distance away from the convention stage on a specially-constructed broadcasting gantry. This placement of the center prompter creates the illusion that the speaker is periodically looking straight into the camera lens and thereby appears to directly address the TV audience watching the televised Convention coverage.

(later to become British Prime Minister), who bestrode stages while speaking seemingly off-the-cuff, having memorized key parts of his speech. This use of multiple off-stage confidence monitors also dispenses with the need for glass teleprompters to be present on the conference stage, thereby reducing "stage clutter", and removing the inevitable restrictions on the speaker's movement and field of vision imposed by on-stage glass prompters. The disadvantage of such a system is that the provision of "giant teleprompters" becomes essential to maintaining the illusion of speaking with apparent spontaneity.
