Social networks and Google+
Google was late to recognize the popularity and advertising potential of social networks such as Facebook and Twitter. Its first attempt to create a social network, Google Buzz, started in 2010 and closed less than two years later. Among several problems, the network was limited to users who had Gmail accounts, and it created privacy issues by featuring a default setting that showed a user’s profile to anyone. Even before Google Buzz had shut down, the company launched Google+ in June 2011, at first to a limited audience and then to anyone. Within a year of its start, the social network service had attracted more than 170 million users. Facebook, by contrast, had taken five years to reach 150 million users.
Nevertheless, Google+ faced a formidable competitor in Facebook, which by mid-2012 had some 900 million users. Facebook users spent far more time on their site, clocking six to seven hours per month, while Google+ users averaged a little more than three minutes per month. Because Facebook did not permit Google’s Web indexing software to penetrate its servers, Google was unable to include the giant social network in its search results, thus losing potentially valuable data from one of the most-trafficked networks on the Internet. Still, the company appeared to be fully supportive of Google+. Seeing the value of games in retaining users on social networks, it quickly released a games area for the service. It also developed innovative features that were not available on Facebook. For example, with Hangouts, users could instantly create free video conferences for up to 10 people. The company also added Google+ pages for businesses to market their products and brands. However, Google+ never supplanted Facebook, and the service was discontinued in 2019.
