From the order "all hands on deck", perhaps so that the captain can address the entire crew from the sterncastle.

In my experience, this is the sort of meeting that completely wastes a shocking amount of everyone's time, and the Flavor-ade that HR always distributes there tastes very strange.

In my opinion, a company-wide mandatory meeting should be held no more often than owner/shareholder meetings, and only for time-sensitive issues that affect the entire company, such that you want everyone to hear that news, spun correctly from your good ol' trustworthy and reliable CEO, instead of getting rumors with varying levels of substantiation from the Internet.

If you want to give out awards and reinforce corporate culture, make that a voluntary meeting, and bribe people to come to it with gratis food and drink, or door prizes, or some form of entertainment.
