Today Google announced that it is shutting down a number of services, including the failed social network Google Buzz, to focus more on Google+.

Google Buzz was a social networking, microblogging, and messaging tool from Google that integrated into Gmail. The service ran into some privacy issues and the company announced it would shut down the service a few months ago.

The Buzz API and content will be absorbed by Google+, and users will be able to view existing posts on their Google+ profile. The service will officially be shut down in a few weeks.

“We aspire to build great products that really change people’s lives, products they use two or three times a day. To succeed you need real focus and thought – thought about what you work on and, just as important, what you don’t work on. It’s why we recently decided to shut down some products, and turn others into features of existing products,” explains Bradley Horowitz, Vice President, Product at Google.

In addition to Buzz, Google is also removing Code Search, which helped people search for open source code, Jaiku, a product acquired in 2007 that let users send updates to friends, and the University Research Program for Google Search, which provided API access to search results for academic researchers. These services will be shut down on January 15, 2012.

And finally, Google will also remove the social components from iGoogle – a customizable homepage – on January 15, 2012, to focus efforts on Google+. iGoogle and its non-social applications will remain intact.

While the removal of these services might not have a great impact on businesses and brands, Google credits lessons from past products, such as Buzz, to the success of current services like Google+.
