Michael Jackson
Death

On June 25, 2009, less than three weeks before his concert residency was due to begin in London, with all concerts sold out, Jackson died from cardiac arrest, caused by a propofol and benzodiazepine overdose. Conrad Murray, his personal physician, had given Jackson various medications to help him sleep at his rented mansion in Holmby Hills, Los Angeles. Paramedics received a 911 call at 12:21 pm Pacific time (19:21 UTC) and arrived at the property four minutes later. Jackson was not breathing and CPR was performed. Resuscitation efforts continued en route to Ronald Reagan UCLA Medical Center, and for more than an hour after Jackson's arrival there, but were unsuccessful, and Jackson was pronounced dead at 2:26 pm Pacific time (21:26 UTC).

Murray had administered propofol, lorazepam, and midazolam; his death was caused by a propofol overdose. News of his death spread quickly online, causing websites to slow down and crash from user overload, and it put unprecedented strain on many services and websites including Google, AOL Instant Messenger, Twitter and Wikipedia. Overall, web traffic rose by between 11% and 20%. MTV and BET aired marathons of Jackson's music videos, and Jackson specials aired on television stations around the world. MTV briefly returned to its original music video format, and they aired hours of Jackson's music videos, with live news specials featuring reactions from MTV personalities and other celebrities.
