1) Endless repetition of the same episodes of a sitcom or commercial on
television.
2) A
radio station playing the same pop

"I used to think that
chick on the Progressive commercial was kind of cute the first 50 times I saw it, now thanks to oversaturation, she's just annoying."
"Foster the
People is so oversaturated on the radio, I will
never buy one of their albums!"
