The company acquired a 7-year xobni to improve the functionality of its mail service

XOBNI's name is the reverse of an English "Inbox" (Inbox), which provides services that can index an e-mail address from all users ' accounts, and then generate an address book containing information about each contact. This includes photos, jobs, history of messages, and postings on Facebook and Twitter by contacts.

Yahoo did not disclose the specific terms of the acquisition. Xobni says the company's existing customers can continue to use the service, which will be integrated into Yahoo's products in the future. Previous media reports said Yahoo's offer was priced at between 30 million and 40 million dollars.

Yahoo says 31 of Xobni's employees will join the company.

Yahoo Mail Service provides the company with significant direct advertising revenue, so the company's investment is not surprising.
