[9] Oxegen attracted significant attention from outside Ireland, with many of those attending travelling from overseas experiencing a "mass exodus" to the festival.

[17] Leagues O'Toole has described it as an "enormously successful, award-winning, established brand [...] aimed at a young audience out for a good time, a post-Leaving Cert rite of passage perfect for acts with big singalong tunes that sound great in the mud".

[19] In April 2014, organisers announced that the Oxegen festival would not be going ahead that year, citing a lack of suitable headline acts.

"[21] The original festival, Witnness, sponsored by Guinness, took place during the start of August with notable headliners, including Oasis, The Foo Fighters and Green Day.

Battles played the biggest festival show of their career at that time in the Pet Sounds Arena during Oxegen 2008.

[30] Each Oxegen has been defined by the attention focused on its own weather, with The Belfast Telegraph referring to 2005 as "the sunny one", 2006 as "the torrentially rainy one", 2007 as "the muddy one" and 2008 as "the so-so one".

[109] Media described the Dublin leg of The Stone Roses Reunion Tour, held in Phoenix Park on 5 July 2012, as a replacement for the year's lack of Oxegen.

[110][111] A Swedish House Mafia concert at the same venue two days later also drew comparisons with the festival, with "Oxegen-like behaviour" culminating in a number of random unprovoked attacks and concerns that "The off-stage events which have dominated the news agenda since the Swedish House Mafia show [...] will forevermore be associated with stabbings and suspected drug deaths rather than the music.

The actual announcement posts were deleted on the same day as negative feedback was so heavy that festival promoters urged MCD to remove it to avoid embarrassment.
