4ZZZ launched its glorious tradition of counting down listeners' 100 favourite songs on New Year's Day 1977. More than 10 years later, 2JJJ in Sydney (which employed many ex-Zed staff) began conducting its own Hot 100. Because 4ZZZ held the rights to the name Hot 100, there was a little bit of legal biffo when TripleJ became a national broadcaster, so they changed the name of their survey to the "Hottest 100".
Chief whip replaced after leadership spill
Queensland MP Scott Buchholz has replaced Mr Ruddock.
Prime Minister Tony Abbott said he is confident with the team now in place.
The sacking of Mr Ruddock came after last weeks failed leadership spill.
However, there are concerns among Liberal MPs that the government will not be able to recover from inner party tensions.
