I read about this in some blog and in newspaper
Bravo Obama about this:
"president Obama was awarded the Nobel Peace Prize Friday morning for what the committee called “extraordinary efforts to strengthen international diplomacy and cooperation between peoples,” especially his work to reach out to the Muslim world and to eliminate nuclear weapons around the globe.
The announcement, less than nine months after Obama took office, sparked immediate questions from reporters in Oslo about whether the Nobel committee was acting prematurely in rewarding a world leader who has outlined a lofty and ambitious agenda but has not yet made many concrete steps toward realizing it.
But Thorbjoern Jagland, chairman of the five-member Nobel committee, said “we have not given the prize for what may happen in the future. We are awarding Obama for what he has done in the past year. And we are hoping this may contribute a little bit for what he is trying to do.”
