Smallest difference in a three year gap this century?

I think the early 2010s was the last era where cable TV was popular. I remember shows like Breaking Bad, Adventure Time, Phineas and Ferb, and My Little Pony were very popular in those years.
Then all of a sudden, in the mid-2010s, it was all about Netflix originals like House of Cards and Orange Is the New Black. Pretty much every cable channel felt soulless by this point too. I'm talking about channels like Disney Channel, Cartoon Network, and Nickelodeon. It seemed nobody cared about them anymore the way they did in the 2000s, and almost all of the shows sucked. Instead, kids were watching Minecraft YouTubers and PewDiePie.
