Rank: 1 in Computer Software
Adobe is famous for developing top-notch multimedia software for web design, digital publishing, and video editing.
The company has become the biggest player in the creative software market, commanding almost half the market share.
Yes, Apple refuses to support Adobe's popular Flash player on its iPhones, iPods and iPads (only on Macs).
But Flash remains spectacularly popular and keeps on growing: 81% of online videos are viewed using Flash; 6 million Flash apps have been downloaded from the Android market and Flash software is installed on 98% of the world's desktop computers.
With a reputation for excellence and a portfolio of many of the most respected and recognizable software brands, it's no wonder the company is greatly admired.
