The series features almost 100 characters, including BIFFO, Dame Enda, Garret FitzGerald, and others based on people from Irish and international public life involved in politics, sport and entertainment.

Nob Nation was reported in the Sunday Independent on 20 January 2008 as being Ireland's most popular podcast of the previous year, with figures showing a total of 736,711 downloads on RTÉ.ie between April and December 2007.

[3] Following a number of complaints about Callan's portrayal of Taoiseach Brian Cowen "swaying and snorting in booze-filled sing-songs about his difficulties in office", the popularity of the slot has "simply exploded" according to RTÉ, with over 250,000 hits each month and making up almost a third of all downloads from RTÉ.ie.

[4] In January 2009, Nob Nation satirised the RTÉ staff pay cut controversy by suggesting Gerry Ryan would try to get out of taking a pay cut by broadcasting for longer but without charging extra for it and that Pat Kenny would contribute to the economy by doing a nixer for free in the RTÉ canteen – to the dismay of all who preferred their full Irish breakfast to the delicacies favoured by the Kenny palate.

[7] Those parodied on the compilation include politicians Bertie Ahern and Enda Kenny, former Republic of Ireland national football team manager Steve Staunton, broadcaster Gay Byrne and newsreaders Bryan Dobson and Colm Murray.

And a third album "Nob Nation Uncensored" was released in the Irish Daily Mail in November 2009, containing tracks not previously broadcast and a series of sketches that had not been played on RTÉ.
