Blogger is a blog publishing service created by Pyra Labs and acquired by Google in 2003. Generally, blogs hosted by Google are under the subspect of blogspot.com. Blogger allows its users to publish their blogs on other servers, via FTP until May 1st, 2010. After that date, all blogs must be stored on Google servers, even though users can use their own site address with Custom URLs. On August 23, 1999, Blogger was launched by Pyra Labs. As one of the first blog publishing tools in the world, Blogger plays a role in popularizing the blog format in the world. In February 2003, Pyra Labs was acquired by Google, making a number of Blogger premium features previously commercialized by Pyra Labs into a completely free service. In October 2004, co-founder of Pyra Labs, Evan Williams, resigned from Google.
