[3] He reported on the Soviet and Warsaw Pact invasion of Czechoslovakia in 1968 for The Irish Times and then edited a monthly news magazine, Nusight in 1969–1970.

He remained editor of Magill until 1983, when he became involved in the relaunch of the Sunday Tribune with Tony Ryan, then of GPA and later of Ryanair.

A series of articles he published in Magill highlighting the links between the Workers' Party and the Official IRA in the 1980s caused him and other journalists to receive death threats.

One led to the establishment of the Planning Tribunal, originally chaired by Mr Justice Fergus Flood; another caused a committee of the Oireachtas to examine the DIRT scandal; another caused an investigation of insurance "churning" by Irish Life, a leading Irish insurance company.

On being given access to the transcripts from 1981, Browne claimed that it was apparent the motivation for the interception of his telephone conversations for the eight-year period had little to do with the security of the State – it was aimed at garnering information on his work as a journalist, entirely aside from his reporting of the IRA.

[12] From 14 January 2007, he presented Tonight with Vincent Browne, a nightly current affairs television show on TV3 before stepping down from this role on 27 July 2017.

[16] Browne later wrote a piece for The Irish Times on why O'Brien "is not a fit person to control INM [Independent News & Media]".

In it he questioned O'Brien's previous threats to sue Sam Smyth and asked "[H]ow plausible is it that the removal of Sam Smyth from a Sunday morning radio programme on Today FM, which Denis O'Brien controls, and his ostracisation now within the Irish Independent to which he is contracted (not one article by him has been published for some months), isn't part of the same campaign which Denis O'Brien and [one of his then representatives on the board of INM] Leslie Buckley, conducted against Sam Smyth in 2010?

"[17] In 2015, after asking were other members of the media wimps, he led a posse of journalists and camera crews into Gorse Hill, the up-market house at the centre of a legal battle.

[20] In October 2010, he was forced to make a public apology to Kenny after jokingly asking whether Fine Gael was requesting that he go into a dark room with a gun and bottle of whiskey.

This was in reference to Fine Gael's position in the polls, where they were in second place to Labour, and a previous leadership challenge to Kenny by Richard Bruton.

[24] In July 2003, writing of the Arms Crisis, he said "the gravest injustice was done to Albert Luykx (a member of the SS during World War II) ...who never had reason to believe that in lending money to the operation and giving otherwise of his services, he was not acting on behalf of the Irish state".

[7] He sold his €2.6 million home in Dalkey in June 2011 to pay off debts incurred from the establishment of Village magazine, and to provide a pension.
