Nightly News | September 10, 2010
>>> and now as we promised, a word about why we are here in this massive studio sound stage tonight where we will be hosting a live special across all the broadcast networks at once, for that matter, across 17 networks in all. it's all called " stand up to cancer ." it's a night to come together against this disease. so those of us who compete each night in the network evening news business are also coming together this one night. my friends katie couric and diane sawyer are both here doing their evening broadcasts. the three of us are coming to host together along with a slew of stars. it is tonight here on nbc at 8:00 eastern and pacific, 7:00 central time . we'd love for you to tune in for it. it's a cause near and dear to us all.
