Hey, big news: consumer electronics giant Sony is going to start selling digital music! Oh, hang on… Okay, so Sony has already tried this digital distribution lark with its Connect service, which flopped badly. However, the company has just announced a three-year plan for a more ambitious digital distribution service, covering music, films and TV shows. The idea is to distribute this content to a host of devices, including computers, TVs, mobile phones, Wi-Fi enabled music and video players, and PS3 consoles. Sony plans to spend $16.8 billion building the distribution platform, but the question is whether it can sign up all the rival studios and labels, rather than just focus on content from other Sony divisions.
