Smile! Thanksgiving Is Instagram's Biggest Day It's officially a new American tradition: Instagraming Thanksgiving. Yesterday, we asked the photo-sharing service how many photos related to the holiday were being uploaded. At around 3 p.m. ET it told us 100 photos a second were hitting the app, but we had a feeling that number would go up as dinner time approached. And we were right. Instagram said today in a blog post that at some hours 200 photos a second were uploaded with a Thankgiving related tag or comment, contributing to a total of 10 million Thanksgiving-themed photos yesterday. "Overall, the day broke all Instagram records as we saw the number of shared photos more than double from the day before, making it our busiest day so far," Instagram said in a blog post today. The service even beefed up server and back-end capacity yesterday to meet the turkey-photo sharing demand. Sure, it's the biggest day Instagram has seen so far, but Christmas is just around the corner. Eggnog photos anyone?
