Search giant Google is celebrating its 25th birthday today with a special doodle. Google Inc. was incorporated on September 4, but for more than a decade the company has celebrated its birthday on September 27.

• The company took a "walk down memory lane" and showcased different doodles to mark this special occasion. 
• Today's ( 27th September) Google Doodle comes with a GIF which turns 'Google' into 'G25gle'. The tech firm said that it was using this day as a "time to reflect" while being oriented towards the future. 
• Google was founded by doctoral students Sergey Brin and Larry Page who met in Stanford University's computer science program in the late 90s. 
• "As they made meaningful progress on the project, they moved the operation to Google's first office - a rented garage. On September 27, 1998, Google Inc. was officially born," it read.
