His WTF-a-thon caused a similar situation, with viewers in the livestream flocking to the sites for the various games being advertised and inadvertently bringing them down. It quickly became something of a Running Gag throughout the livestream.
The effects of TB's Colbert Bump can be seen live in video (recorded during the WTF-a-thon) in TB's run of Realm of the Mad God: behold more than 30 out of the possible 85 players in a server congregating around TB as his personal army. As a fan remarked, the effect of a "WTF is..." increases a game's population by 4000%.
TB is causing a lot more attention to the game God Hand since he said that "if I find out one of you doesn't like this game, I'll personally come to your house and kill you."
TB also caused a lot of popularity for Kung-Fu Jesus's LP of God Hand as a result of his video, by way of linking it in the description.
He Lampshades this in his WTF is.. of DLC Quest, saying that he can weaponize it by tweeting about the dev's site & crashing it.
He has actually hit the "like" button on a few Retsupurae videos, which has lead to spikes in their popularity.
His video on Brothers: A Tale of Two Sons, where he praised the game as the best game he has played in his life so far, single-handedly put it to the Steam top ten best selling games, even pushing it to number six ahead of Saints Row IV for a while. It was 81st before the video.
