Moving to mobile devices is always hard and expensive.
Yahoo has to compete with other mobile apps and companies. Yahoo didn't convince mobile users to use their apps instead of competitor's apps. There was no advantage to the mobile users to watch videos on Yahoo instead of Youtube for example. There was no advantage to use Yahoo Mail instead of Gmail. There was no advantage to use Yahoo News instead of Google News.
Yahoo should have moved to mobile apps years ago, when the market was still young and growing. It has become too late as Google, Facebook, Twitter, etc already have a lock in with mobile apps. All Yahoo can do now is try and catch up with the others. What they need to do is innovate new features no other app has instead of trying to catch up. Find some new niche market and make an app for that.
