"Since we started Stand Up to Cancer in 2008, social media has exploded, creating a whole new way to connect," Katie Couric, a Stand Up to Cancer co-founder, said in a statement Wednesday. "So in an unprecedented way, we'll have plenty of stars reaching out to donors via social media, thanking them through Facebook messages, digital shout-outs, Instagrams and tweets. In other words, this year, we are so 2014!"
