Twitter names Jack Dorsey permanent CEO

(Reuters) - Twitter Inc named co-founder and interim Chief Executive Jack Dorsey as its permanent CEO, ending months of speculation about who would take the reins at the company. Dorsey will remain head of fast-growing mobile payments company Square, which he also co-founded, potentially setting up conflicts of interest. Twitter had previously said the CEO job would be a full-time position, which seemed to exclude Dorsey if he continued to run Square.
