Barack Obama’s historic election victory set bloggers abuzz.
In the wake of winning the 2008 U.S. presidential election, Obama was mentioned in almost 20% of all blog discussions, Nielsen Online reported Wednesday.
In comparison, John McCain was referenced by just 6.3% of all blog entries posted on November 5, according to Nielsen.

On the eve of the presidential election, both candidates made hefty boosts in their advertising in seven key swing states: Colorado, Florida, Georgia, Missouri, Ohio, Pennsylvania, and Virginia.
On Sunday, Nov. 2, McCain ran just 708 TV ad units in those seven states — 48% fewer than the 1,463 ad units Obama ran that day. 
But on Monday, Nov. 3, Obama’s lead in these key battleground states shrank to 79% — or a margin of 1,510 ad units, after McCain’s campaign increased the number of TV ad units it ran in those …

During the final weekend preceding the presidential election, Sen. Barack Obama ran 77% more TV ads than Sen. John McCain (5,947 vs. 3,358) in seven key swing states: Colorado, Florida, Georgia, Missouri, Ohio, Pennsylvania, and Virginia.
Despite trailing Obama in terms of the total number of TV ad units placed, McCain showed a much larger percentage increase in TV advertising from the previous weekend (Friday October 24 thru Sunday, October 26) to this past weekend (Friday, October 31 thru Sunday, November 2).  
McCain bumped his TV ad units up by 76% overall in the seven battleground states Nielsen tracked, while Obama increased his advertising …

Television viewing on Election Night has changed dramatically over the years, considering the expansion of technology and the number of different channels available to the average home. In 1960 for example, in the close race between John F. Kennedy and Richard Nixon, most U.S. homes had only a few channels available so the Election Night returns captured virtually all the audience with more than 65% of all homes tuning in. Now with more than 40 channels available to the average home, the percentage of homes watching political coverage …

Amid an extraordinarily media-driven presidential campaign, the Internet has loomed large, influencing everything from fundraising to fact-checking.
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, …

With the presidential election less than a week away, both candidates are easing back their advertising in seven key swing states: Colorado, Florida, Georgia, Missouri, Ohio, Pennsylvania, and Virginia.
McCain increased his ad units by small margins in Florida, Pennsylvania, and Virginia on Thursday, Oct. 30.  He reduced the number of ad units he ran in Colorado by 1.5%, in Georgia by 31.9%, in Missouri by 1.8%, and in Ohio by 3.8%.
In comparison, Obama boosted his ad units slightly in Georgia, Missouri, Pennsylvania, and Virginia on Thursday.  Meanwhile, he reduced the …

The simulcast — the first of its kind since Ross Perot ran a political telecast on the eve of Election Day in 1996 — aired on CBS, FOX, NBC, Univision, BET, MSNBC, and TV One between 8pm and 8:30pm EDT.
Perot’s 1996 telecast drew almost 22.7 million viewers.
On an average Wednesday night, the networks that aired Obama’s telecast draw a combined average of 30.3 million average viewers during that half-hour daypart.
In comparison, the final debate between the two presidential candidates …
