Today is Google’s 21st birthday: a little retrospect.

Today (September 27th) is Google’s 21st birthday. It is also the theme of today’s Doodle Logo. This large technology company was officially established in 1998 and was only a search engine company. After 2001, Google began to acquire different types of technology companies to expand their range of services. Youtube, Google Map, and the Android operating system, which have become part of the lives of many people, are services that Google has acquired from other companies and have evolved to date. Google has also been involved in the mobile phone market in recent years to produce Pixel series phones. On October 15th, Google will hold “Made By Google” conference, and there will be Google’s latest hardware news.
