March Madness is officially here! The 2019 NCAA Tournament comes to life during the Selection Sunday show, but before they figure out the field -- and before you bust out your (sure-to-win-the-office-pool this year) bracket -- you must first figure out who the heck you're making picks on this year.

Such is why the hubbub is made each year about Selection Sunday, the day (which, you guessed it, falls on a Sunday) in which the field of 68 teams is unveiled. The 2019 NCAA March Madness Selection Show is at 6 p.m. ET Sunday. In other words, it's happening right now, so be sure to watch it via one of the methods below.
