Facebook plans to let users buy music and other virtual products on its Web site, the company said Wednesday, expanding its sources of revenue as the company seeks to turn its huge popularity into fiscal profit.

Separately, Google will let users sample and buy songs directly from its search results page with a service it plans to announce next week, according to reports. The move comes as Google looks to hold its dominance against Bing, which has stolen around 9 percent of the U.S. online search market since its launch earlier this year, according to Internet monitoring companies.

Songs and official sports icons are among the new virtual gifts Facebook will add to its store, the company said on its blog. Users in the U.S. will be able to pay US$0.10 to send friends a song that can only be listened to online, or $0.90 to send a copy that can be downloaded and transferred, the company said.
