BUT the vast majority of buyouts are small and are for the purpose of finding talent, and also the odds of a buyout producing a long-term impact are small. Look at all the acquisitions yahoo has done over the past 2 decades and they, I think, all failed. They bought Mark Cuban's company Broadcast.com for $5.7 billion in 1999, which is now a redirect to the yahoo homepage. Which I think makes it the most expensive domain name ever purchased.
HPE (Hewlett Packard Enterprise) owns autonomy.com which redirects to their website. They paid $11.7 billion USD for a company named Autonomy in 2011. HP was forced to make a $8.8B writedown on the purchase already the following year, and today nothing but the domain name remains at HPE.
