1. Disney Acquires Pixar – Breathing Life into Animation

In 2006, The Walt Disney Company acquired Pixar Animation Studios in a $7.4 billion all-stock deal. Before this merger, Disney was struggling to maintain its edge in animated movies, while Pixar had been delivering back-to-back hits like Toy Story and Finding Nemo.

2. Facebook Buys WhatsApp – Redefining Global Communication

Facebook’s $19 billion acquisition of WhatsApp in 2014 raised eyebrows due to the sky-high valuation. However, this move was a masterstroke in global domination.

6. Dow Chemical and DuPont Merge – Reshaping Chemicals
