Internet firms Facebook Inc and AOL Inc are discussing a strategic alliance aimed at boosting their online advertisement business, the New York Post said, citing sources.

The two companies have been talking for several months about a partnership that would allow Facebook to tap AOL in selling online advertisements, the New York Post said, citing three separate sources.

One possibility for AOL is being named a "preferred media partner" to Facebook, a source told the Post.

"We do not comment on market rumors," an AOL spokesman told the newspaper. Facebook also declined to comment to the Post on a potential partnership.

Both could not immediately be reached for comment by Reuters outside regular U.S. business hours.
