Facebook membership hits 500 million

The number of people using Facebook has hit the 500 million mark, meaning one in every 14 people on the planet has now signed up to online social-networking service.

"As of this morning, 500 million people all around the world are actively using Facebook to stay connected with their friends and the people around them," Facebook founder Mark Zuckerberg said in a blog post.

"This is an important milestone for all of you who have helped spread Facebook around the world."

To celebrate, the California firm introduced an application that lets members of the online community "tell the incredible stories of the moving and interesting ways they’ve used Facebook."

Examples given by Zuckerberg included NATO Secretary General Anders Fogh Rasmussen jogging with Facebook fans during his term as Danish prime minister and a US woman using the service to battle breast cancer.

"Our mission at Facebook is to help make the world more open and connected," Zuckerberg said.

"Stories like these are examples of that mission and are both humbling and inspiring. I could have never imagined all of the ways people would use Facebook when we were getting started 6 years ago

More Businesses Finding Customers on Social Sites

Smaller companies most successful at social acquisition

While many marketers struggle with how to measure social media marketing return on investment, some businesses are finding at least one hard metric where their efforts have paid off—customer acquisition.

According to a February–March 2010 survey from office services firm Regus, smaller companies see the most success, with nearly half of small businesses around the world having acquired a customer through social networks. Large companies were less successful, but more than a quarter had seen social success through customer acquisition. This was despite large companies being more likely to devote budgets to social marketing.

The survey of senior managers and business owners from around the world found customer acquisition varied by country, with the US coming in the lower half of the pack. Overall, 40% of businesses studied had acquired a customer through a social site, but only 35% of US businesses said the same.

“While the most popular function of these networks remains that of keeping in touch with contacts, businesses are also successfully acquiring new customers, supporting their retention efforts and interacting with customer groups,” said Sande Golgart, vice president at Regus, in a statement. “Organizations who have not yet ventured into the world of social networking may be missing out on sizeable business opportunities.”

In January 2010, Hubspot found that more than 40% of companies using social media marketing had acquired a customer through the channel. The Regus survey, which was not limited to businesses using social marketing, suggests that number may be slowly climbing.

Who Spends Most Time on Facebook?

How age, income and ethnicity affect time spent social networking

The Nielsen Company reported in June that, on average, the global consumer spends about 1 in every 4.5 minutes online on blogs or social networking sites. According to a report by market researcher Morpace, among US Facebook users time on Facebook rises to 1 in 3 minutes spent online.

Unsurprisingly, despite Facebook’s growing appeal to older users, 18- to 34-year-olds spend the most time on the site per week, at 8.5 hours out of 22.4 spent online. Weekly Facebook time drops to 4.6 hours among users ages 55 and older, representing a lower proportion of that group’s average of 21.5 hours per week on the internet.

Broken down by race and ethnicity, Morpace found Facebook usage heaviest by Asians. Not only did that group spend the most hours per week on the site, but they also devoted the greatest percentage of their weekly internet time to Facebook (39.6%, compared with 35.1% among blacks, the second-highest group). Hispanics spent the fewest hours on Facebook, and even compared with their low average time online came in last.

While the Morpace report showed a decline in both total time online and time on Facebook as incomes rose from less than $50,000 up to $100,000, affluent Facebook users making at least $100,000 annually spent the most time on the site and on the web as a whole.

In Q1 2010, comScore found that the visitors who spent the most time on Facebook also spent the most money online. Targeting users who not only spend large amounts of time on the site but also devote a large proportion of their total online activity to the social network could translate to going after the most lucrative portion of the audience.
