1972: United States president Richard Nixon had around 3,700 hours of secretly taped meetings and phone conversations, which took place in the White House and other locations.
The infamous Watergate scandal blew up in 1972 after several “burglars” were caught breaking into the offices of the Democratic National Committee at the Watergate Hotel in Washington, DC, in an attempt to plant bugs.
Nixon resigned two years later.
1992: A 20-minute phone call between Princess Diana and her childhood friend, James Gilbey, emerged three years after it was apparently made on New Year’s Eve in 1989.

1993: Just a month after the divorce of Prince Charles and Princess Diana, phone recordings between Charles and Camilla Rosemary Shand (now Duchess of Cornwall) were released, revealing explicit phone conversation.

1998: Over 20 hours of phone conversations were recorded allegedly between former White House intern Monica Lewinsky and US civil servant Linda Tripp.

2005: The now-defunct News of the World (NoW) printed a story about Diana’s son, Prince William, injuring his knee, prompting royal officials to complain to police of a possible voicemail hacking.

The two pleaded guilty and were jailed, and the scandal led to the closure of the paper in 2011.
2014: A phone conversation was leaked purportedly between US Assistant Secretary of State Victoria Nuland and US ambassador to Ukraine Geoffrey Pyatt.
