In November 2014, Vice News launched its French-language version. In October 2015 Vice hired Josh Tyrangiel to run a daily Vice News show for HBO. Tyrangiel had recently left Bloomberg, where he was reported to be "a divisive figure who was both admired and despised during his six years there." Tyrangiel named Ryan McCarthy, formerly an assistant editor of The New York Times, as editor-in-chief of Vice News. In May 2016, it was announced that Tyrangiel had also been given control of the weekly Vice on HBO show as well as Vice News. As the announcement was made, Tyrangiel promptly laid off much of the news staff. In an interview given the previous week, Vice Media founder Shane Smith called Tyrangiel "a murderer," foretelling a "bloodbath" in digital media. On May 24, 2016, a change in leadership at Vice News resulted in the laying off of some 20 editorial and production staff members. That June, Tyrangiel touted various new hires he had brought aboard as part of his team. In December 2016, it was announced that Vice News had entered into a partnership with The Guardian newspaper that will include Guardian journalists working at Vice's offices in East London and contributing to the two HBO television programs currently on the air. It will also include allowing The Guardian access to Vice's video production skills with content distributed to its millennial-skewed global audience.
