3rd Logo (Startup and Closedown, January 1, 1963-October 4, 1987 for startup, January 1, 1963-September 29, 1991 for closedown)


Visuals:
 * Startup: On a background with glass sheets and bars, one glass bar slides diagonally to the bottom-right, and another horizontally to the left. The video then fades to two other glass bars horizontally sliding at opposite directions then outwards. Two other glass bars then slide to the bottom, one sliding deeper than the other. After that, two glass sheets horizontally slide at opposite directions, going past each other. It then fades to a lot of vertical glass bars shining, then to two glass bars sliding outwards. Another two glass bars slide inside a box with green walls, orange ceiling and blue floors. Then, the box is shown in a different angle, with glass bars on top of it. Four glass bars then slide onto each other, forming a square. At this point, the following text starts to scroll into the video: "TBS 東京放送 映像周波数 183.25メガヘルツ 映像出力 50キロワット 音声周波数 187.75メガヘルツ 音声出力 12.5キロワット 第6チャンネル 6 JOKR-TV" ("TBS Tokyo Broadcasting Video frequency 183.25 megahertz Video output 50 kilowatts Audio frequency 187.75 megahertz Audio output 12.5 kilowatts Channel 6 6 JOKR-TV"). While those text were scrolling, the video fades to one  glass bar sliding to the right, and one glass bar and sheet sliding to the left. Multiple glass bars then rapidly move top to bottom. In the back ground is a large number "6" It then fades to a rainbow "6" amongst a bunch of glass bars, which then switches to a bunch of towers overlooking it. A white "6" shows up. Then in the next clip, the camera moves down, first showing the white "six", then the rainbow "6". After that, it fades to three "6" bars, with (in order from left to right) the colors being yellow, blue and red rotating counter-clockwise until the number "6" is clearly visible.

Variants: From 1963 to 1973, this ID was in black and white. In 1972, "メガサイクル" ("megacycles") was replaced by "メガヘルツ" ("megahertz"). On October 4, 1987, when TBS began 24-hour broadcasting, the startup was no longer being used and the closedown was shortened to 30 seconds at the end, and was also used for startup.

Technique: Live-action models combined with cel animation.

 * Startup: Same as the 1961-1963 ID.
 * Closedown: A more somber version of the startup's music.
