A taping system (aka recording device) installed in the office of the President helped lead to the downfall of President Nixon. While Nixon was president, a recording device was installed in his office to record phone and in-person conversations. When being accused of having ties to the Watergate break-in, the Supreme Court ruled that Nixon must release his taped conversations. These conversations had incriminating evidence and showed Nixon's true intent as president. Ultimately, the evidence discovered by these recorded conversations lead to Nixon's resignation.
