YouTube co-founder Chad Hurley is stepping down as CEO of the world's most popular website for watching video.
Hurley's decision to give up the leadership role at the 5-year-old site formalizes a transition that has been in the works for some time as YouTube's owner, Google Inc., asserted more control.
Salar Kamangar, one of Google's earliest employees, has been running YouTube's day-to-day operations for the past two years while Hurley concentrated on the site's design and relationship with its users.
Hurley, who is 33 years old, intends to remain a YouTube adviser and officially turn over the CEO's role to Kamangar.
Google bought YouTube for $1.76 billion four years ago, enriching Hurley and his fellow co-founders Steve Chen and Jawed Karim. Chen and Karim already left YouTube.
