Gmail has successfully completed the journey of five years. Gmail was launched in April 1, 2004. That time a typical webmail account could only store about ten megabytes of mail, where Gmail came up with 1,000 megabytes (1 gigabyte) of free storage – more than 100 times what most other free webmail services offer that time.
Within last 5 years, there has been many changes and new features added to Gmail and probably Gmail is now an essential part of our day to day life.
Best wishes to Gmail team for making such a great product.
