His radio broadcasts have led to the release of regular podcasts, several CDs and appearances on prime-time television programmes such as The Saturday Night Show on RTÉ One.

[5] 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.

[8] Following some 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 "simply exploded" according to RTÉ, with over 250,000 hits each month and making up almost a third of all downloads from RTÉ.ie.

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.

Callan Kicks the Year proved a hit with viewers on RTÉ One television, and its ratings beat Christmas specials by rivals The Mario Rosenstock Show and Irish Pictorial Weekly.

[17] The show once again proved controversial in its portrayal of the President and his aide leading the Sunday World to publish a front-page story on the programme before it aired.

In October 2011, Callan[20][21] was allegedly assaulted by Kerry football star Paul Galvin late at night in Kehoe's Pub, Central Dublin.

[23] The media speculated on the reason behind the alleged incident, reporting that Callan had recently mimicked Galvin asking Taoiseach Enda Kenny to man-up by giving him a body-wax on radio.

'[24] and that Galvin had texted Callan before an appearance on The Saturday Night Show in relation to "gay jibes" the satirist had directed at him.

[28] Callan then appeared on The Saturday Night Show for an unprecedented second consecutive week[29][30] to defend himself against accusations of homophobia[31][32][33] by coming out on live television.
