In May of 2016 Twitter was being traded for less than 20 dollars a share. And had bottomed out under 15 dollars in 2016. It wasn’t until Trump announced his candidacy that Twitter started rising
“The first real offer for Twitter came in 2007, when Yahoo tried to buy the nascent social network for a then-whopping $12 million. In 2008, on the eve of that year’s presidential election, Mark Zuckerberg upped the ante by offering a few hundred million for the company that he would later refer to as a “clown car that drove into a gold mine and fell in.” Ashton Kutcher tried to purchase a piece, too, while poolside in Los Angeles, naturally, as the founders of Twitter nervously sat next to Demi Moore, who was sunbathing in a black bikini. Zuckerberg came back a couple of years later for another unsuccessful overture. Former Vice President Al Gore made his informal offer after a long night in which he and a couple of co-founders got drunk on tequila at his home in the St. Regis Hotel. Google’s Larry Page made his acquisition attempt inside a Google conference room, having drawn the blinds, even though the conference room was on an upper floor, to ensure that no one could see him talking to a Twitter founder. During his tenure as the C.E.O. of Microsoft, Steve Ballmer showed interest to another Twitter founder while sitting on the porch of Bill Gates’s home. Apple even considered an investment that would give it a stake in the company.”
