This logo uses the Peignot font (same as that of The Mary Tyler Moore Show), and is nicknamed the "Pinball" logo because of its electronically-produced logo sounder being described by many as being akin to a pinball machine.
The first variation of this logo was nicknamed the "V of Doom" due to it coming off as unsettling to many viewers. Eventually, the "V of Doom" logo was replaced with a much calmer variation, nicknamed the "V of Steel".
On January 1, 1990, for the first time in 13 years, the stylized "V" symbol was retired in favor of a new logo. The logo was nicknamed the "Wigga Wigga" logo. It was used for the Paramount Pictures logo's byline until 2010, even after the logo for the new Viacom was introduced.
On December 31, 2005, Viacom split into two companies, the present-day Viacom and CBS Corporation. It was folded into CBS Paramount Television (now CBS Television Studios), but can still be seen thanks to reruns of classic shows.
