Louis CK is popular in the same way that a band like Arcade Fire is popular. Arcade Fire sells lots of albums and is highly respected by other musicians, but the band isn't as well known among most of America as a top 40 staple like Rihanna. This represents sort of a "high" pop-culture, which would include popular indie music acts like Arcade Fire, TV shows like Mad Men and Breaking Bad, and comedians like Louis CK and Jim Gaffigan.
