NBC Uni sites have record traffic surges

User increase stems from oil spill coverage, 'Today' videos

A pair of NBC Universal digital properties both enjoyed record traffic surges this past May, driven in part by interest in the BP oil spill and the volatile stock market.

First off, MSNBC.com -- a joint venture between NBCU and Microsoft -- delivered a record 154 million total video streams in May, a healthy surge of 59% versus last year. That up tick in video usage occurred as many users logged on to view news clips tracking the oil spill in the Gulf of Mexico as well as numerous "Today" show videos and the new daily recap show "Today in 2 Minutes."

Meanwhile, CNBC.com reached an audience zenith in May as well; per comScore, the site attracted over 6 million unique visitors for the first time who generated 326 million page views, also a record. Those figures are miles from just a few years ago, when CNBC.com struggled to reach 1.5 million unique users (according to Nielsen Online).

CNBC.com's reach boost was driven in part by Wall Street's May 6 meltdown, which resulted in the site's biggest traffic hour ever. The same can be said for CNBC's mobile, which saw its page views soar by 154% at the 3 p.m. EST hour that day. Overall, CNBC's mobile traffic generated a record 100 million page views in May, including both its mobile website and iPhone app.
