OMG!! In the UK it is called The Great British Bake Off and it is very popular. Basically all of my friends watch it. People are really obsessed about it here and it has got loads of people to start baking (again). I was so confused for a second when you made that post because I thought "is there some other British baking TV show that I haven't heard of, like on ITV?".
It's so jarring to see it called The Great British Baking Show on PBS... I need to lie down. This is like Harry Potter and the Philosopher's Stone all over again.
