Top level management from RTÉ - along with members of the RTÉ Board - were before the Oireachtas Public Accounts Committee on Thursday.
In advance, Minister for Media Catherine Martin had warned those appearing to engage in "as transparent a manner as possible".
Here is what we learned from the PAC meeting:
Reconstitution of the Executive Board
In his opening statement to the Oireachtas Public Accounts Committee, RTÉ Deputy Director General Adrian Lynch told members that there will be a "reconstitution" of the Executive Board.
This was communicated to him last night by the incoming Director General, Kevin Bakhurst, who is due to start on 10 July.
What exact changes might be made to the top level of management in RTÉ was not made clear.
Separately, the chair of the RTÉ Board, a body which is not involved in the day-to-day running of the broadcaster, told politicians that the way payments to Ryan Tubridy were recorded and presented in the RTÉ accounts appeared to her to be "an act designed to deceive".
When Ryan Tubridy found out
Many have asked if Ryan Tubridy was made aware of a potential issue around payments prior to his decision to leave The Late Late Show.
At the PAC meeting, Mr Lynch said that it was "possible" that he did know.
Chief Financial Officer Richard Collins informed the committee that he was first made aware of a potential issue on 7 March, following an audit by Deloitte.
Mr Collins informed the then Director General Dee Forbes on 8 March, the committee heard.
Mr Tubridy announced his intention to step down from The Late Late Show on 16 March.
"So, Ryan Tubridy could well have been informed by somebody that these concerns had been raised?" Sinn Féin's John Brady asked, and this "could have influenced" his decision to step down.
"Based on the information from yesterday, it's possible," Mr Lynch said.
Mr Tubridy has previously stated that the payments issue did not have any bearing on his decision to step down.
Patrick Kielty's pay packet
In a statement, Patrick Kielty revealed that he will be paid €250,000 per 30-show season and had signed a contract for three seasons.
As part of this package, he will be receiving a one-off payment of €20,000 to cover the pre-production and rehearsals from now to September.
Mr Kielty confirmed that he has also waived his expenses.
At the PAC hearing, Labour TD Alan Kelly was told that the expenses element of the deal was worth €50,000.
However, this has now been removed from Mr Kielty's original contract.
An end to the 'talent'
RTÉ's top earners are referred to as "the talent".
In her opening words, RTÉ Board chair Siún Ní Raghallaigh said that it was time "to consign this term to the dustbin".
She explained that "words matter and the term, as it is currently used, reinforces a 'them and us' culture in RTÉ".
"It implies some have greater worth than others," she said.
Top 100 salaries
There was also a commitment at the PAC hearing to publish the salaries of RTÉ's top 100 earners. This would include both on-air individuals and management.
Ms Ní Raghallaigh said that it would happen "as soon as is practically possible".
At present, RTÉ only publishes the remuneration of the top 10 on-air earners.
Meanwhile, Sinn Féin's John Brady insisted on knowing the salary of RTÉ's Chief Financial Officer.
"I believe my salary is around €200,000 base salary plus a car allowance of €25,000", Mr Collins said.
Other executives were not called upon to disclose their pay, however the chair of the RTÉ board has committed to publishing these figures.
The Barter Account
The use of the RTÉ Barter Account, to pay Mr Tubridy an extra €150,000, was the focus of questioning for many politicians today.
Mr Collins reiterated that he had first been informed by Deloitte of a potential issue on 7 March.
He told members that he brought this to the attention of Ms Forbes, who he said explained to him that they were "consultancy invoices relating to services provided during Covid-19" by Noel Kelly Management.
Mr Collins relayed this back to Deloitte, adding that they "were not happy" with the explanation.
Meanwhile, Mr Collins revealed that more than €1m went through the account over a decade.
The Public Accounts Committee heard RTÉ used it to pay €275,000 for tickets and travel for clients for the Rugby World Cup, IRFU tickets and the Champions League Final.
Ms Ní Raghallaigh said this was "outrageous".
Not informing the minister
Ms Ní Raghallaigh apologised to Minister for Media Catherine Martin for not informing her that she had previously asked Ms Forbes to resign.
Alan Kelly told Ms Ní Raghallaigh that this was not acceptable.
"I don't think any minister would put up with that," Mr Kelly said of Ms Ní Raghallaigh's failure to tell Minister Martin that Dee Forbes had been asked to resign.
He asked ex-chair of the RTÉ Board Moya Doherty if she would have told the minister.
"Yes," Ms Doherty replied.
Taxpayer 'defrauded'
At the heart of this controversy is the fact that the public was misled, in terms of Mr Tubridy's true remuneration.
Fine Gael's Alan Dillon focused on whether the commercial arrangement used to pay Mr Tubridy an extra €150,000 was used to deliberately conceal payments.
RTÉ's Chief Financial Officer Richard Collins told members: "My own opinion is maybe the taxpayer was defrauded."
Throughout these committee hearings, RTÉ witnesses have stated that while the misstating of the true salary of Mr Tubridy was wrong, there was nothing illegal about what was done.
