BIGBANG 是 YG 投注長時間心血所打造的第一組男孩團體，光是準備期就花了 4-5 年的時間。他們出道前，YG 便透過《 Documentary BIGBANG 》這個生存選秀節目，將 BIGBANG 成員的選定過程呈現給大眾，因此很多人 在BIGBANG 以一個完整的團體出道前就開始關注他們。
對此，梁玄錫的說明如下：「 BIGBANG 出道時 YG 的經紀能力還不強。身為沒有分量的中小企業其實也滿擔心的。應該要讓他們常上節目，但也沒自信能做到這點，因此我們非常迫切需要新的企劃。於是我們想了個點子，並向平常有在來往的電視台台長說明，這位台長比其他電視台幹部還開明，他說他想試試非一般電視台競爭的內容，就算讓公司花錢他也想嘗試新的東西。 網路發達後，想看現場直播的歌謠節目觀眾愈來愈少，大家都想輕輕鬆鬆地看自己想看的歌手，那種為了看喜歡的歌手等上好幾小時的時代已經過了，所以台長認為應該跟著新媒體的潮流走。」
這場生存選秀中有 G-Dragon、太陽、T.O.P、大聲、勝利、張賢勝等六人參加。G-Dragon（本名權志龍）和太陽（本名董永培）在 2000 年小學六年級時就已經是 YG 的練習生；T.O.P（本名崔勝炫）則是梁玄錫偶然在弘大某夜店看到他的表演而挖掘成為 YG 的練習生；大聲（本名姜大聲）則是從小夢想成為藝人，長期在文化電視台旗下的MBC 學院學習並累積實力，而後參加 YG 主辦的選秀，合格後成為 YG 的練習生；勝利（本名李升炫）從國中起就在「逸話」舞團活動，在光州是有名的舞者，和大聲一樣，是參加 YG 的選秀才成為練習生；張賢勝也和大聲、勝利一樣，希望能以歌手出道而參加 YG 的選秀成為 YG 的練習生。
