In the spirit of the Christmas Truce of 1914 when Germans and British soldiers laid down their arms to exchange food and souvenirs in observance of the holidays, two age-old rivals from the tech industry make peace, if only for one day. Peace on 5th was a live event filmed on location at New York City’s iconic 5th Avenue and was performed by a choir of 37 real employees from the tech industry.

Over the years, these two companies have had a relationship that’s teetered from bitter rivals to amicable collaborators. This year, Microsoft used the holiday season as a catalyst for peace.
