Prince’s surprise appearance at the 72nd Annual Golden Globes — where the artist presented the award for best original song to John Legend and Common, for “Glory” from the film “Selma” — drove the most social conversation on Facebook and Twitter on Sunday evening.

Ironically, the notoriously reclusive Prince does not have accounts on the two social services, having deleted them last fall. (He misidentified the category in his prefatory remarks as “best original score.”)

Over all, on Twitter, users posted 2.6 million tweets during NBC’s 8-11 p.m. ET telecast Sunday. That’s up from 2.4 million for last year’s Golden Globes. But it still trailed the 2014 Oscars, which produced 11.2 million tweets — and 13.9 million people viewed a total of 1.04 billion tweet impressions; that included host Ellen DeGeneres’ much-r...ted selfie.

At the Golden Globes Sunday, the No. 1 moment on Twitter was Prince presenting best original song to Legend and Common, followed by Matt Bomer winning best supporting actor in a miniseries for “The Normal Heart” and Billy Bob Thornton winning best actor in a miniseries for FX’s “Fargo.”

Meanwhile, on Facebook, 8 million people worldwide had over 17 million interactions related to the Golden Globes on Sunday. That’s up substantially from 4.1 million people and 7.2 million interactions for last year’s Globes. However, the 2015 kudocast still trailed last year’s Oscars, for which 11.3 million users had a total of 25.4 million interactions.

On Facebook, Prince’s presentation to Legend and Common for best original song was also the top moment, followed by Joanne Froggatt winning best supporting actress for TV drama for “Downton Abbey”; Amazon’s “Transparent” winning best TV comedy or musical; Billy Bob Thornton winning for “Fargo”; and Ricky Gervais presenting Amy Adams with the award for best actress in a motion picture musical or comedy.
