In tandem with the holiday-themed “Making a Difference” segments airing this week on NBC Nightly News, the newscast’s digital team launched a companion Web site on msnbc.com to help spread good news.

The site offers an archive of Making a Difference segments, extended interviews, other video elements, blogs, and information on how users can help profiled organizations and nominate organizations and individuals.

NBC Nightly News senior producer Sam Singal, who oversees the Making a Difference site, said, “The intention is to create a national community of viewers for a conversation about these stories.”
