Was Browsing TV Tropes...

 So, I Was Browsing TV Tropes's Article Called "Repeating Ad" 

It means "The very odd practice of airing the same commercial twice, or two commercials advertising the same product, in the same commercial break."

While Browsing The Cartoon Network Section Of This Trope, I Came Across Some Teen Titans Go Examples!

• Cartoon Network repeatedly ran ads for Teen Titans Go! that proclaimed it "Your New Favorite Show". It was hard to escape; it got to the point where the ad aired on Toonami every break, it played on other channels, and one blogger reported that it had been playing on a loop on queue line monitors over at Six Flags! This campaign was enough to irk those who aren't fans of the new series.

• On a repeat of the Teen Titans Go! episode "Where Exactly on the Globe Is Carl Sanpedro?" on August 14, 2020, the ad for Snap Ships played twice in one commercial break.

• During the Teen Titans Go! crossover with DC Super Hero Girls on May 31, 2021, an ad for Got Milk? repeated at least 3 times during commercial breaks.

As of May 2019, the practice of airing two Empire Today ads during the same local slot is fairly common on Cartoon Network airings of Total DramaRama. It also happens on other shows, too, like when two of their ads played during the local slot in between airings of two Teen Titans Go! episodes ("Butt Atoms" and "The Bergerac") during the Teen Titans Go! vs. Teen Titans Marathon  on February 17, 2020

• On DIY Network, an ad for Teen Titans Go! where kids got excited over "The Pee Pee Dance" played every half-hour during the summer of 2015.

And Thanks, TV Tropes, Your My Favorite Resource!
