Google

1997-1998 (beta testing)
This logo was used during Google's developing stage at Stanford University. Google was, in fact, originally named BackRub.

1998
This logo was used only for a month. Back then, the uppercase "G" was green.

1998-1999
In 1998, the uppercase "G" at the beginning of the wordmark was colored blue, the logo is a bit smaller, the logo is now floating instead of indented in, and an exclamation point was added at the end of the wordmark, possibly to mimic the Yahoo! logo. This logo reappeared as an easter egg when the user searched on Google "Google in 1998."

1999-2010


Launched in 1999, this is probably one of the most well-known logos on the Internet. The font on this logo is Catull BQ and the exclamation point was removed. On some outdated browsers (such as Internet Explorer 5), this logo is still used instead of the next couple logos below.

2010-2013
Launched in 2010, this logo is just like the previous logo, except that the colors on the letters now have brighter tones and the shadows behind them have been reduced. This logo first appeared during a beta testing of the site's new look on November 8, 2009, before it fully premiered in 2010. This logo is still used on some pages despite the fact it was succeeded by the next logo, and it is still being used on some services by Google including Google Earth, Google Checkout and Google Maps.

2013-2015


In 2013, the logo was given a more two-dimensional and flatter effect to fit more in line with Google's most recent products. Some differences from the previous logo include serifs with more straightened acute angles on the uppercase "G," a more straightened "l" and a connected horizontal bar on the "e". It is still used in certain conditions.

2015-present


The new logo was designed by graphic artists from across America including Google's internal studios working together within a week-long sprint in New York. The criteria the new logo had to meet is as follows: This redesign was mainly influenced by a trend in technology companies to simplify their logos to make them more recognisable on the growing number of electronic devices which use their services. With this redesign, a new typeface called Product Sans was introduced as the font for the logo and to be used Google Apps, a refresh of the green, yellow and red colours used on the wordmark to better contrast each other and a smaller image size change from 14,000 bytes to 302 bytes to suite low bandwidth areas. As with former logos, the "e" in the logo is slightly askew (as emphasised by the nudge it's given in the Google Doodle and intro video) as a reminder that Google will always be an unconventional company. The new logo is also accompanied by a new favicon, changed from a lowercase "g" to an uppercase "G" sporting the colors of the main wordmark. Another new branding asset introduced with the rebrand is a set of circles colored with the colors of the wordmark which act as a method of communicating to the user in Google's search app.
 * A scalable mark that could convey the feeling of the full logotype in constrained spaces.
 * The incorporation of dynamic, intelligent motion that responded to users at all stages of an interaction.
 * A systematic approach to branding in our products to provide consistency in people’s daily encounters with Google.
 * A refinement of what makes us Googley, combining the best of the brand our users know and love with thoughtful consideration for how their needs are changing.

White logos
White versions of the Google logo are used during times of great tragedy. Instances when the white logo has been used include the Polish aircraft disaster which killed President Lech Kaczyński, the Qinghai earthquake and the Gansu mudslide of China. White logos would also appear if you customized the main page of Google by adding a background with the now-decommissioned iGoogle. The white version of the Google logo also appears on Google Maps.

Doodles

 * Please help by adding the logos on google.com/doodles to the Doodles pages.

On various days of the year, Google changes from their default logo to a stylized one with significance to the date (i.e. Thanksgiving). These are known as Google Doodles. To look at these Doodles, see the list of pages below, each referring to a specific year.

2010–2012


This icon still appears on some pages.

2012–2015
The icon was changed in November 2012. This logo is basically an inverted version of the 2008 icon, a lowercase "g" on a blue rounded-rectangle.

2015-present


Following its logo change in 2015, the new Google icon now uses an uppercase "G" with the four different colors from the main logo. There are also the new Google dots and the new search button.
