These awards represent the supposed apex of recognition for the creative, intellectual, and athletic arts, the validation of a person's years of hard work and creativity... a work's mark of superiority whatever the medium... recognition by both the establishment and your peers.
So why is it that so many artists and works, some even considered among the best of all time, have gone award-less?
An Award Snub is when a work or person is denied the acclaim of a popular award that it seems to deserve, through action malicious, unintentional, overly reactionary, out-of-touch, or anti-populist on the part of award voters. The reaction to the folks at home is the same: "That didn't win? And that did?!" It's a real life case of Dude, Where's My Reward?.
Of course, it could also be for entirely innocent reasons. If two or more great works come up for the award that year, someone's going to have to be disappointed. There Can Be Only One, after all.
If an individual has gone for long enough with continued snubs, expect an award to be given (almost out of pity) for a recent perhaps-inferior work or at the very least, a life-time achievement award. For more information on that phenomenon, please see Consolation Award.
In the worst case scenario the unrewarded artist dies and (unless he/she completed something before their death that's deemed eligible and worthy) the voters never have another chance to make things up to her/him; posthumous honorary awards just don't exist. This is an unfortunate overlap with Posthumous Popularity Potential.

Heated debates on if a work was actually snubbed have often occurred and can also degenerate into Complaining About Shows That Won as well as Take Thats to shows that lost, so because of that we won't be listing such examples here. If you really want some ideas, check out these off-site articles about The Oscars, The Emmys, and The Grammys. See also the People's Choice Awards, which were created at least in part as a way of addressing/averting this.
