DreamWorks Animation, the tiny Hollywood studio behind films such as Shrek, Madagascar, and more recently, How to Train Your Dragon, could provide a unique way for SoftBank to bolster its wireless offerings. The Wall Street Journal reports that the company, and its outspoken billionaire CEO Masayoshi Son, could use content from the animation studio to make Sprint more competitive in the US. SoftBank completed its acquisition of Sprint last year, and has looked for ways to take on AT&T and Verizon.
