While it is "downloadable content", it isn't an extra that people can voluntarily download from the PS / Xbox Store. It is an update that will automatically be installed for every user. Please, stop refeering to it as a DLC. (Henriquedematos (talk) 00:50, November 17, 2013 (UTC))
Rockstar themselves refer to it as DLC, and is it DLC, because it is content that the game downloads via a patch. But wait a minute, you say that it is DLC, but we shouldn't refer to it as DLC. Wat.
It appears I was mistaken. Rockstar are actually referring to it as a content update. It IS technically DLC, but as you said, it's not explicitly downloaded by players. I have updated the article.
The title of this page should be 'Beach Bum Update', as that's what Rockstar are oficially referring to it as.
