Are you sure what GameExplain said was really a joke? From what a friend told me of watching the video. The only had a bit of small laughter after they talked about Shadow's popularity with one of them saying "Really? Even more then Tails?". I didn't watch it so maybe they said that sarcastically. But to be honest it's not really a joke, depending on your point of view. There are ways you could see Tails or Shadow more popular then the other. Perhaps in the general Sonic fanbase Shadow is more popular since he has much louder fans that are more on the diehard side. But Tails also has his fans outside of the Sonic fandom that are more familiar with the Classic sonic games. Non-gamers would know Tails more then Shadow to be honest. So there's different ways to look at Tails and Shadow's popularity.
