The surprise news that the head of CBC English services, Richard Stursberg, was leaving his post dominated Twitter in Canada on Friday.

Within hours of the official announcement, Richard Stursberg was the top trending topic in the country.

The news of the immediate change at the top of CBC provoked more of a discussion on Twitter other more usual topics, such as Emma Watson and Megan Fox.

No reason was given for the departure. In a statement, Hubert T. Lacroix, president and CEO of CBC/Radio-Canada, talked of Stursberg’s record and added:

We are in the midst of developing a new strategic plan that will guide CBC/Radio-Canada through the next five years. This is the opportune time to bring new leadership to English Services and to ensure alignment of the senior team on the future of the public broadcaster.

The interim replacement is Kirstine Stewart, general manager, CBC Television.
