For the fourth year in a row, IBM (IBM -8.25%) has placed first in International Data Corp.'s worldwide rankings for market share for enterprise social software, IBM announced yesterday.

The ranking measures success in the field of integrating social media into corporate practices.

IBM says its social networking platform, IBM Connections, offers one-click social collaborations through an easy-to-use interface. IBM's social business clients include Prudential Insurance, Lowe's, and Electrolux. According to the company's website, more than half of Fortune 100 companies have used the company for social business solutions.

IDC reported that the market segment for social business grew to $1 billion in 2012. This is a 25% jump compared to the year prior, and IBM's general manager for social business, Alistair Rennie, believes that the company "is accelerating [the social business] transformation and helping change the way leaders are working."
