Beyond the content of the speech, some media coverage focused on the manner in which it spread through the Internet. Video of the speech "went viral," reaching over 1.3 million views on YouTube within a day of the speech's delivery.[71] By March 27, the speech had been viewed nearly 3.4 million times.[72] In the days after the speech, links to the video and to transcripts of the speech were the most popular items posted on Facebook.[72] The New York Times observed that the transcript of the speech was e-mailed more frequently than their news story on the speech, and suggested that this might be indicative of a new pattern in how young people receive news, avoiding conventional media filters.[72] Maureen Dowd further referenced the phenomenon on March 30, writing in her column that Obama "can ensorcell when he has to, and he has viral appeal. Who else could alchemize a nuanced 40-minute speech on race into must-see YouTube viewing for 20-year-olds?"[73] By May 30, the speech had been viewed on YouTube over 4.5 million times.[74] The Los Angeles Times cited the prominence of the speech and the music video "Yes We Can" as examples of the Obama campaign's success in spreading its message online, in contrast with the campaign of Republican (then) presumptive nominee John McCain.[74]
