In this clip (go to 3:16) on the Daily Show Jon Stewart brings up that Newt Gingrich announced his candidacy for 2012 elections via Twitter. He makes fun of the fact that this candidate is older and is trying to use all these new media sources to gain popularity with the younger generation. He questions why he is ditching television and newspaper and the first time he announces his candidacy is on a tweet that has a link to a youtube video, and the youtube video isn't even done well.
I think its important to know your audience. I think Mr. Gingrich should have first utilized traditional media and then new media to show that traditional media is what he knows best and it is still important and then reaches out to the younger generation- and they both can be released at the same time, but traditional media is still crucial and will really die out quickly if people don't use it.
