Mercedes-Benz
The 'Mercedes' name was registered right back in 1902, but at that time there was no logo or trademark to accompany it. The idea for the 'Star' logo came when Paul and Adolf Daimler, the two sons of the company's founder (and then in charge of the business), remembered that their father had once used a star symbol in his family correspondence.

Their father, Gottlieb Daimler, had been technical director of the Deutz gas engine factory from 1872 until 1881. At the beginning of his employment there, he had marked a star above his own house on a picture postcard of Cologne and Deutz, and had written to his wife that this star would one day shine over his own factory to symbolize prosperity.



In June 1909 the company registered both three-pointed and four-pointed stars as trademarks. Although both designs were legally protected, only the three-pointed star was ever used. From 1910 onwards it began to appear at the front of the cars as a design feature on the radiator.

The three points of the star were supposed to represent Daimler's ambition of universal motorization: "on land, on water and in the air".

Over the years the logo evolved, to include the 'Benz' laurel wreath, and then, in 1923, the three-pointed star enclosed in a circle was registered as a trademark.

Since then it has changed little, and is now a powerful symbol and integral part of the Mercedes-Benz brand.


BMW
The BMW logo is symbolic of a white propeller blade, against a blue sky. It reflects the origins of BMW as a maker of military aircraft engines during the first world war.

It is a good example of a strong brand-led company retaining the best of its heritage in the form a of distinctive logo design, without placing too much emphasis on the origins of the logo itself
Playboy
Hefner said that he chose the rabbit as a mascot for its "humorous sexual connotation," and because the image was "frisky and playful."
An urban legend started about Hefner and the Playmate of the Month because of markings on the front covers of the magazine. From 1955 to 1979 (except for a six month gap in 1976), the "P" in Playboy had a number of stars printed in or around the letter. The legend stated that this was either a rating that Hefner gave to the Playmate according to how attractive she was, the number of times that Hefner had slept with her, or how good she was in bed. The stars, which ranged in number between zero and twelve, actually indicated the domestic or international advertising region for that particular printing
Durex
The name, which the London Rubber Company trademarked in 1929, is a portmanteau of "Durability, Reliability, and Excellence", though some people mistake it as being "Durable Latex"
Burger King
The famous Burger King "bun halves" logo made its debut in 1969 and endured well into the 1990s. As its name implies, it was meant to resemble a hamburger: the logo had two orange semi-circular "buns" surrounding the name, which was the "meat" of the logo. In 1994 BK updated the logo with a graphical tightening, replacing the aging "bulging" font with a smoother font with rounded edges. In addition, all secondary signing, such as roof and directional signs, was also updated with new rounded font.
In 1999, BK again revised its logo. The new Burger King logo is a stylized version of the original "bun halves" logo. BK changed the color of the restaurant's name from orange to red lettering, while leaving them sandwiched between two yellow bun halves. The new logo also tilts the bun halves and the font on an axis, has a smaller "bun" motif and wraps the burger with a blue crescent whipping around the buns giving it a more circular appearance. Most restaurants did not acquire newer signs with the new logo, menus, and drive-thru ordering speakers until 2001. Again all secondary signage was updated with the new logo and type face, and all sign posts were repainted to match the blue coloring of the new crescent from their original black.[78]
