Not long ago, HTC posted six consecutive months of record revenue thanks to strong demand for its Android-powered smartphones. The company’s record run came to a screeching halt in October last year with the release of Apple’s iPhone 4S. HTC’s fourth quarter earnings fell, missing Wall Street’s expectations, and the rough patch continued in the first quarter of 2012. To compound matters, the latest study conducted by ad network Chitika shows that the troubled handset maker’s usage share has declined by more than 60% in the past five months from 18.22% to 7.28% based on traffic across its network. At the same time, Apple’s share has increased by 64% from 46.84% to 76.88% and other Android vendors such as Samsung and Huawei have recorded continued modest growth. HTC is betting big on its flagship One X smartphone, and it hopes the handset, along with the rest of its One-series phones, will help the company rebound.
