On Tuesday night, after tying some lights around the palm trees outside my front door, I ventured down the hill to Sunset Tower, the iconic, century-old Hollywood landmark and onetime A-list pied-à-terre, for the annual Warner Bros. Discovery holiday media party. This was the first (for me, anyway) in a gauntlet of mediaco cocktail-and-canapés soirées that stretch from now until a week before Christmas in Los Angeles and New York. These events, which cap the professional year with a healthy dash of civility and cheer, are effectively a party favor for the more obsequious members of the trade press, an olive branch to more critical chroniclers, and, in their best iterations, a reminder that no matter what happens in the occasionally contentious arena of press and public relations, we’re all adults trying our level best to notch wins and sustain losses, and thus all deserving of a Christmas truce.
