10 things that happened the last time Serena Williams was not World No. 1

Donald Trump was just a reality TV star ( a very, very rich one)

Property magnate Donald Trump, before 2015, was known primarily for two things – his wealth and excess in showing it off, and the business-themed reality TV show he helmed, The Apprentice.

Although Trump had donated to political campaigns before, he had not been active on the political scene personally.

Things have changed drastically since – the flame-haired billionaire has become somewhat of a phenomenon in his run to the United States presidency. The Republican nominee who is fighting to succeed Barack Obama to the presidency, Trump is inexplicably popular among certain demographics and has become somewhat of a media staple, dominating airwaves and headlines worldwide.
