Big Brands Like Facebook, But They Don't Like to Pay

Everybody wants to be liked. The question for Facebook Inc. is how much advertisers are willing to pay for the opportunity.

Facebook's estimated market value, now in the neighborhood of $70 billion, is founded on the belief that companies will spend big to advertise on the site. Facebook's revenues, which come largely from ads, were $1.6 billion in the first half of this year, up $800 million from a year earlier. But most of its ads were for small advertisers, such as local businesses and small-scale websites, according to comScore Inc. Facebook is under pressure to grow its advertising on a grand scale, and to snag the sort of big brand names who now drive billions of dollars to TV, radio and print campaigns. U.S. consumers spent 15% of their online time at Facebook in September, according to comScore. But Facebook is expected to capture just 6.4% of total online ad spending this year, according to estimates by research firm eMarketer Inc.
