CBS Corporation

1971–1976


This is the first Viacom Logo and was seen on television from 1971 to 1976. This logo is nicknamed the "Pinball Logo" because of the music which sounds like a pinball machine. This logo has a lot of variations with the colors and no speed variations. It does have a higher pitched variation. It is considered a very scary logo by most people (due to the primitive animation), but compared to the next logo, it's nothing.

1976–1990
This logo is known as the "V of Doom". It says "A Viacom Presentation" and the V zooms on on the viewer. This is said to be the scariest logo ever created along with Screen Gems and its "S". This, however, is a favorite among people due to its avalanche of varieties such as filmed and videotaped versions, a monochrome variant, and even a variant with the previous logo's music.

1986–1990


This is nicknamed the "V of Steel". It has varieties, but not as many as the previous logo including a warp speed variant. This logo may be scary due to the THX-like sound and resemblence to the previous logo, but it's harmless.

1990–2005


In 1990, for the first time in 14 years, the infamous stylized "V"﻿﻿ that has connected Viacom to hate has finally been put to rest as the new logo, the Viacom snake, nicknamed "Wigga Wigga" by some, was introduced. The viacom snake was used for the Paramount Pictures byline. The first variant originally had soothing music, changed to a new-era sounder. In 2000, a newer, slightly creepier variant was created, nicknamed "RoboCom". After 2005, Viacom's logo no longer existed, it was folded into CBS Paramount Television (now CBS Television Productions), but can still be seen thanks to reruns of classic shows.
