NBC.com, which grew 312% month-over-month, saw the largest September increase in video viewers, followed by FOX Broadcasting and ABC.com, with 165% and 105% growth, respectively, Nielsen Online reported Thursday.

“A combination of series and season premiers, political news and parodies, and coverage of the financial crisis all contributed to increased online video viewing for the television networks in September,” Jon Gibs, vice president, media analytics, Nielsen Online, noted. “Consumers are increasingly relying on the Web to catch up on content they missed when it aired on television and the networks are beginning to capitalize on this trend.”

Total video streams in a variety of entertainment categories also increased last month.

Overall, the number of unique viewers streaming video online increased 6% — from 117,916 viewers in August to 125,061 in September.  Meanwhile, total video streams increased 10% month-over-month — from 8.06 million in August to 8.89 million in September.

YouTube, Yahoo! and Fox Interactive Media were the top brands, ranked by video streams, during September.

Nielsen Online recently analyzed the online presidential campaign, examining online advertising by the candidates, Web traffic and online video viewing at both campaign’s sites, and blog buzz related to the election.

Online Advertising
Senator Barack Obama’s campaign ramped up its online advertising in mid-September. Image-based ad impressions by the Obama campaign grew 202% from September 15 to 22 — and by another 94% by September 29.

In mid-October, Obama’s campaign also stepped up its sponsored link advertising, surpassing McCain’s sponsored link advertising for the first time.

In contrast, Sen. McCain’s online advertising push came in the weeks just before the Republican National Convention. McCain boosted image-based ad impressions by 261% between August 11 and 22, but after announcing Palin as his running mate, scaled back his display advertising. Between August 25 and September 7, McCain’s image-based online advertising dropped by 85%.

Web Traffic To Campaign Sites
Unique visitors to BarackObama.com outpaced those to JohnMcCain.com nearly two to one in September. The unique audience at BarackObama.com went from 6.1 million in August to 7.9 million in September (+31%).

During the same time period, JohnMcCain.com’s unique audience grew by 56% — from 2.7 million to 4.2 million unique visitors.

Video Viewing Via Campaign Websites
Total video streams at JohnMcCain.com surged by 175% in September — from 1.2 million streams in August to 3.2 million in September. Unique video viewers at the McCain’s site also increased 175% last month, from 475,000 viewers in August to 1.3 million in September.

In comparison, video streams at BarackObama.com saw less dramatic growth (+60%). Visitors to the site viewed 1.3 million streams in August, and 2.0 million streams in September. Unique viewers at Obama’s site also increased by 35% in September, from 824,000 viewers in August to 1.1 million last month.

Candidate Blogosphere Buzz
Online buzz about the two presidential candidates is increasing as Election Day approaches. In general, spikes in blog buzz during October coincided with the presidential and vice presidential debates on October 2, 7, and 15.

In the days leading up to and following Obama’s October 29 TV infomercial, online discussions of Obama have outpaced those referencing McCain.

Candidate Online Brand Associations
In online discussions, McCain and Obama are most closely associated with each other, followed by their running mates.

After that, McCain is most closely associated with “Sarah Palin,” “campaign,” and “debate.” Obama is also closely associated with “Sarah Palin,” as well as with “vote” and “president.”

Nielsen Online’s proprietary Brand Association Maps chart the attributes most closely associated with each candidate in online discussions. In general, BAM analysis provides an unaided, unsolicited, real-time barometer of consumer perceptions of and attitudes toward a topic discussed online.

Although McCain has tried to downplay several public relations challenges that occurred during his campaign, the terms “Katie Couric,” “Interview,” and “David Letterman” are as closely associated with him as “reform,” “economy,” and “Freddie Mac.”

Similarly, Obama’s efforts to distance himself from real estate developer Tony Rezko and Rev. Jeremiah Wright failed — in the online realm, at least. Obama is as closely associated with “Rezko,” “Plumber,” and “Wright” as he is with “economy,” “financial,” and “reform.”

Television
-Men typically watch less TV than women their age — with one exception: male teens actually watch more TV than female teens.  Men ages 18 to 34 tend to watch more cable and pay channels, while women gravitate to broadcast networks.

-When it comes to sports programming on TV, men 18-34 are more attentive viewers (+12%) than women of the same age.  But when non-sports programming is on, the reverse is true: males 18-34 are 6% less attentive than their female counterparts.

-In general, men 18-34 are less attentive viewers of both sports (-8%) and non-sports (-10%) TV programs than older men ages 35 and up.

-Men 18-34 are also more receptive to product placements within TV programming than females their age; they report 26% higher brand opinion improvement for advertisers integrated into TV programs.

Online
-Online streaming videos of full-length TV episodes hold the attention of men 18-34 much more than the same programs on TV.

-In general, men 18-34 view more Web pages each month than women their same age (2,353 vs. 2,305 in August 2008).  Men 18-34 also view 63% more individual video streams than women their age (1.4 million vs. 893,000 streams in August 2008).  For their part, women typically spend more minutes watching videos online than men (4.1 minutes vs. 2.4 minutes), who prefer short-form videos on consumer-generated media sites like YouTube. 

Mobile
-Male mobile subscribers ages 18 to 34 are three times as likely as average mobile subscribers to watch video on their phones, and twice as likely as average mobile users to access the mobile Web.

-In Q2 2008, male mobile subscribers ages 18-34 sent and received more than twice as many text messages (531 texts on average, per month) as phone calls (246 calls on average, per month), while women 18-34 made slightly more mobile phone calls than men their age (251 vs. 246 calls per month).


Video Games
-Men ages 18 to 34 averaged approximately 19 gaming sessions in August, with the average session lasting about 66 minutes.  Among all males, men 18-34 accounted for 35% of all minutes played on gaming consoles in August.

-In comparison, women 18-34 logged fewer gaming sessions in August (just over 10, on average), but — like their male counterparts — averaged about 65 minutes of play per session.  Women 18-34 accounted for 39% of all minutes played by females on gaming consoles in August.
