What webshow does Sheldon Cooper host?

Sheldon Cooper hosts the webshow Fun With Flags.

The fictional program reflects Sheldon’s enthusiasm for vexillology, the study of flags. He presents flag facts, historical details, symbols, and cultural observations with the intense seriousness he brings to physics and nearly every other subject.

Amy Farrah Fowler frequently appears alongside Sheldon, making the show one of their shared activities. Their exchanges reveal both Sheldon’s encyclopedic knowledge and his difficulty handling disagreement, improvisation, and criticism. The webshow also gives the series a way to explore Sheldon and Amy’s developing relationship through a hobby they both enjoy.

Fun With Flags is not the same as a general science or physics program. The title is deliberately precise: its subject is flags, while Sheldon’s professional field is theoretical physics. The show is presented as an online production within the sitcom, not as a real standalone web series hosted by Jim Parsons.
