With Buzz, Google Plunges Into Social Networking

On Tuesday, Google introduced a new service called Google Buzz, a way for users of its Gmail service to share updates, photos and videos. The service will compete with sites like Facebook and Twitter, which are capturing an increasing percentage of the time people spend online.

The links shared on those social networks are also sending a growing amount of traffic to sites across the Web, potentially weakening Google’s position as the prime navigation tool on the Internet.

Separately, Facebook plans to announce on Wednesday that it is improving the live chat service on its site by allowing it to be integrated into other services like AIM, AOL’s instant messaging network, which is among the most popular in the United States.

Buzz is Google’s boldest attempt to build a social network that can compete with Facebook and Twitter. The service is built into Gmail, which already has 176 million users, according to comScore, a market research company. And Buzz comes with a built-in circle of friends, a group that is automatically selected by Google based on the people that a user communicates with most frequently in Gmail and on Google’s chat service.

Like other social services, Buzz allows users to post status updates that include text; photos from services like Google’s Picasa and Yahoo’s Flickr; videos from YouTube; and messages from Twitter. Analysts say many of its features mimic those of Facebook.
