Comeback kid: How Taiwan's MediaTek rose to mobile chip dominance

TAIPEI/ HSINCHU, Taiwan -- When Rick Tsai took the CEO position at MediaTek more than four years ago, industry experts and investors all thought he had been handed a poison chalice.

The company's operating margin hit a historic low and it reported its first ever loss in its smartphone chip business. Making matters worse, MediaTek's most important chip offering of 2017 was a flop, with very few smartphone makers agreeing to use it.
