Google

         

          Google is an American multinational corporation specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software.

In 1998, Sergey Brin created a computerized version of the Google letters using the free graphics program GIMP. The typeface was changed and an exclamation mark was added, mimicking the Yahoo! logo."There were a lot of different color iterations", says Ruth Kedar, the graphic designer who developed the now-famous logo. "We ended up with the primary colors, but instead of having the pattern go in order, we put a secondary color on the L, which brought back the idea that Google doesn't follow the rules."

In 2010, the Google logo received its first major and permanent overhaul since May 31, 1999. The new logo was first previewed on November 8, 2009, and was officially launched on May 6, 2010.It utilises an identical typeface to the previous logo, but the "o" is distinctly more orange-colored in place of the previously more yellowish "o", as well as a much more subtle shadow rendered in a different shading style. On September 19, 2013, Google introduced a new "flat" (two-dimensional) logo with a slightly altered color palette.On May 24, 2014 the Google logo was updated, the second 'g' has moved right one pixel and the 'l' has moved down and right one pixel.The old 2010 Google logo is still used on some pages, such as the Google Doodles page.

Pepsi

                  Pepsi (stylized in lowercase as pepsi, formerly stylized in uppercase as PEPSI) is a carbonated soft drink that is produced and manufactured by PepsiCo. Created and developed in 1893 and introduced as Brad's Drink, it was renamed as Pepsi-Cola on August 28, 1898, then to Pepsi in 1961, and in select areas of North America, "Pepsi-Cola Made with Real Sugar" as of 2014.

The Pepsi logo is a simple circle. The top half is red, the bottom half is blue, and a wavy white line runs through the center. The colors intentionally represent the American flag, but that’s just scratching the surface of this simple globe. Pepsi spent hundreds of millions on their current logo, which is very similar to their previous ones, but tweaked in a way that it (apparently) means a lot more.When submitting the new logo, the branding agency hired by Pepsi presented a 27-page document explaining the many, many connotations their design represented. According to this document the new logo represents the Earth’s magnetic field, feng shui, Pythagoras, geodynamics, the theory of relativity, and plenty more. Makes you wonder if the logo is working as intended or if the branding company lied their way into a big fat check.
