Microsoft and Yahoo will today announce a deal between the companies to connect their instant messaging (IM) networks so users on each can communicate with one another using text and voice chat.
Yahoo and Microsoft will now command upwards of 44 percent of the market, according to research firm Radicati Group, putting new pressure on market leader AOL, which holds around 56 percent market share with AIM and ICQ. And according to recent comScore Media Metrix numbers, MSN Messenger and Yahoo! Messenger together reach 33.5 million unique users each month, more than the 23 million running AIM.
It's rumoured Microsoft is also in talks with Time Warner to make a similar agreement for AIM. More info at BetaNews.
