The Saturn one (Geiz ist geil!) was unavoidable in the 2000s. The Edeka one (Supergeil) was a viral social media hit in the mid-2010s. I can understand missing out on the second one if you weren't paying attention to German social media but if you were old enough in the 2000s to know what an ad is I have no idea how you managed to avoid that. And even then you'd have at least heard of the phrase because the ads put it back into popular discourse with right-wing politicians chastising consumers for their "Geiz ist geil" mentality. The Sparkasse ads were also from the mid-2010s. They were basically very beige board meetings of the "08/15 Bank" (08/15 meaning "standard issue" or "run of the mill" in German though the exact origin is disputed - likely somehow relating to the MG 08/15 machine gun of WW1). You couldn't really sit through an ad break without seeing one.
