More money is pouring into online video.

Visible Measures, a video analytics and advertising platform, says it has secured $21.5 million in its most recent funding round--the latest big investment in the digital video space.

Among the video start-ups landing big funding rounds over the last year are Ooyala, which just got a $35 million investment, Taboola (which brought in $10 million), Brightroll ($30 million), Switchcam ($1.2 million funding), and YuMe ($22 million). 

Visible Measures' current investment round brings total funding to more than $65 million, reports TechCrunch. Investors included publishing giant Advance Publications--owner of Conde Nast--as well as DAG Ventures and other venture capital firms.

Founded in 2005, Visible Measures says its client list includes blue-chip advertisers P&G, Ford, Goldman Sachs, and Microsoft.

Founder and CEO Brian Shin says in the press release that the company is "on track to surpass 300% revenue growth for our second consecutive year."
