New York—Attention, b2b marketers and agencies: Show us your best and most innovative social media marketing programs. Our editorial team will choose the best submissions and recognize them in the March 12 issue of BtoB and at an awards ceremony in San Francisco on March 20.

We're currently accepting entries in the following categories: Best use of Facebook, Best use of Twitter, Best use of LinkedIn, Best use of mobile, Best viral video, Best corporate blog, Best closed community and Best social media integrated program across multiple channels (tech and nontech).

Integrated, video and mobile campaigns must have debuted in February 2011 or later; we will not consider campaigns entered last year. Although Facebook pages, Twitter and LinkedIn accounts, blogs and closed communities can have a creation date prior to February 2011, we will only consider materials distributed via these platforms February 2011 and later.

In addition, our readers will have the opportunity to vote online for their favorite entries from a tech and nontech company, and we'll reveal their People's Choice winners at the award ceremony.
