The group owns a number of national newspapers in Ireland: the Evening Herald, Irish Independent, Sunday Independent, Sunday World and the Irish Daily Star. The chief executive is Anthony O'Reilly, who was recently knighted by the British monarch. Some INM titles, especially the Sunday Independent and Irish Independent, are perceived to have a pro-British slant, especially by republicans.

Unison.ie, one of Ireland's premier online brands, was launched by Internet Ireland on February 4th, 2000. In a pioneering move, the Unison.ie portal united over 27 leading Irish newspaper titles, to create Ireland's largest on-line content resource.

The Irish Independent is Ireland's best-selling daily newspaper. Unusually, it is published in both tabloid and broadsheet formats. It was formed in 1905 as the direct successor of the Daily Irish Independent, an 1890s pro-parnellite newspaper. The Irish Independent was launched by William Martin Murphy, a controversial Irish businessman, staunch anti-parnellite and fellow townsman of Parnell's most venomous opponent, Bantry's Timothy Michael Healy.

The Evening Herald is a tabloid evening newspaper published in Dublin, Ireland by Independent News & Media. It is published Monday-Saturday, and has three editions — City Edition, City Final Edition and National Edition. Despite its name, its early editions are usually available by late morning.
