The Era (2009-unknown) when a teen pop sensation became an epidemic. Every website had at least one comment involving Justin Bieber, Justin Bieber merchandise was everywhere you looked, and his songs played over and over on every Radio Station, every Elementary/Middle school had a numerous number of preteen girls wearing Justin Bieber clothes. Similiar to the Michael Jackson Era, or The Elvis Era, except they actually had talent.
Dave: Did you comment on that Youtube video I showed you last night?

Greg: I was going to, but due to the Bieberdemic all of the other comments involved Justin Bieber, so I didn't even bother.
