This document discusses the evolving relationship between tech startups and corporations from 2000 to 2015. It notes that in 2000, startups posed minimal disruption to corporations and online retail was less than 1% of the total retail market. However, by 2015, tech startups had grown significantly in size and funding, online retail grew to 14% of the market, and startups began disrupting major industries like transportation, banking, and automobiles. As a result, corporations shifted from seeing startups as threats to actively partnering with or acquiring startups to gain access to their innovation and understanding of new markets.
