It's one of the first wars of its kind. But in the end, Hollywood actor Ashton Kutcher beat out CNN in a battle to gain over one million followers on Twitter.
Kutcher told talk show host Oprah Winfrey on Friday that "there are giant things you can do on this platform at 140 characters at a time."
Winfrey -- who used Friday's live broadcast to send out her first tweet "HI TWITTERS . THANK YOU FOR A WARM WELCOME. FEELING REALLY 21st CENTURY ." -- admitted she doesn't really know what Twitter is -- but spent most of her show responding to messages she received.
Before Winfrey's first tweet, she already had over 75,000 people following @oprah on Twitter.
"Now I've joined Twitter. Here's my first -- it's called a Tweet? I'm stepping into the Twitterverse!" Winfrey said. "It's too cool. I'm still not sure I really get it. I left my building today and my doorman said I hear you're Tweeting today."
Winfrey received tweets from George Stephanopoulos, Jimmy Fallon, Shaquille O'Neal and Ellen DeGeneres, who tweeted, "Oprah Winfrey, what are you doing on here? Shouldn't you be working on our cover?"
Kutcher, or @aplusk on Twitter, had nearly 2,000 followers more than CNN when he reached the million milestone earlier this morning.
"We found out that CNN was on TV and Anderson Cooper was going off on how CNN has to win this thing, so we decided to go live on the Web (to gain support," Kutcher said.
"I didn't necessarily say I want a million people following. What I thought was really interesting was that in some ways this is a commentary on the state of media." Kutcher said. "You -- through your own stream -- can actually have your own voice as loud as a media network. I thought that it was kind of like an uprising of the Internet."
Kutcher waged war earlier this week after noticing that he had nearly as many followers on Twitter account as CNN.
If he won, Kutcher said he would donate 10,000 mosquito nets to stop the spread of Malaria and ding-dong ditch CNN's honcho Ted Turner's house.
During Friday's show, Winfrey pledged $200,000 to buy 20,000 mosquito nets.
