Microsoft just launched a new MSN service called msnNOW, which the company says is designed to surface breaking trends from across the web, show what people are saying about the trends and why they matter.

“msnNOW scours real-time sources, including Facebook, Twitter, Bing, and BreakingNews.com, so you can stay up on what everyone is talking about and join the conversation,” a Microsoft spokesperson tells WebProNews.

“Whether you’re looking for the latest election trends or celebrity gossip, you can easily sort through topics that you care most about, including entertainment, sports, lifestyle, news of the day and finance,” the spokesperson says. “And, the ‘Biggest Movers’ feature lets you keep track of the day’s most buzzed about and discussed topics from millions of analyzed tweets, comments, and searches, letting you see what’s on the way up and what’s about to be old news.”

“You can access msnNOW whenever and wherever, including on your PC, mobile device, tablet, Facebook or Twitter,” the spokesperson adds. “For more information, go to the MSN blog post and MSN Virtual Press Kit for the video, screenshots, and to learn more about the people behind msnNOW.

I don’t know how many trend services we really need, but this one is does have a leg up on some other ones given that it is a combination of search trends as well as trends from Facebook and Twitter.

The launch follows the recent launch of a new MSN iPad app.
