Refresher around just how quickly MySpace is falling:
– Traffic has declined 44% in a recent month from a year ago, to 37.7M unique visitors in the U.S
– The News Corp. unit that houses Myspace showed an operating loss of $156M in the recent quarter, mostly related to a severe drop-off of ad revenue at the site

On Wednesday about a dozen parties interested in purchasing MySpace will take a look at the company’s books before opening up more serious discussions, discussions not expected to come to a close soon. All Things D expects negotiations to continue for several weeks. Companies rumored to be at the table: continued partnership with News Corp, music video network Vevo, as well as private equity houses Providence Equity and Silver Lake.

Not on the list: Zynga, Criterion Capital (private equity company that brought AOL’s Bebo social network last year), Facebook, Google, AOL, and Yahoo!. Boston’s mobile social network MocoSpace was mentioned months ago as being a suitable buyer, but All Things D made no mention of the company.
