Facebook rolls out video ads, aims to capture part of TV-marketing budgets

Facebook will allow more marketers to run video advertisements on its website, provided the world's No.1 social network deem them to be of high-enough quality.

Facebook and social media rivals like Twitter are increasingly trying to grab a slice of lucrative TV-marketing budgets as they try to sustain rapid growth. That market is considered crucial to supporting Facebook's growing market valuation and poses a potential long-term threat to traditional TV networks.

The 15-second video ads, which appear in newsfeeds and will play automatically with sound muted, will become available to a limited number of marketers over the next few months, Facebook said on its official blog.

The price that marketers pay to run a video ad on Facebook will be determined by the size of the audience as measured by measurement firm Nielsen, Facebook added. Marketers will be able to choose specific times of day for their spots and will be able to target ads according to age and gender.
