Blizzard Inopportune Release Dates

Is it just me or does it seem that Blizzard has a habit and history of releasing new content/expansions the exact same time as new school/college semesters start?

I dont know, but it seems to me like every expansion since Wotlk has been almost intentionally released the exact same week as the majority of U.S new college/school terms begin...

Anyone else notice this trend or am I just crazy lol
