When Is NCAA Selection Sunday? Where to Watch and Live Stream as March Madness Begins

March Madness is edging ever closer as college basketball teams battle it out for a spot in the 68-team tournament, which begins next week.

The 2018 NCAA Tournament will be announced on Sunday, during TBS' Selection Sunday Show, which begins at 6 p.m. EST. The show will also be available via live stream at NCAA.com or via the March Madness app and will mark the first time since 1982 that CBS will not broadcast Selection Sunday.
