AOL-Time Warner (2018) – $84 billion

Despite its initial promise, the deal faltered due to incompatible corporate cultures, strategic missteps, and the dot-com bubble bursting. The merger resulted in significant losses for both companies, with AOL eventually spun off in 2009.

In the same year as the AOL-Time Warner merger, Vodafone, a British telecommunications giant, acquired Germany’s Mannesmann in what was the largest merger in corporate history at that time.

This deal propelled Vodafone to the forefront of the global telecommunications industry, solidifying its position as one of the largest mobile network operators in the world. The acquisition highlighted the growing importance of the telecommunications sector and set the stage for further industry consolidation.
