Terry Mackin is out as president of the Univision Communications' TV station group after just five months on the job.

"I can confirm that he decided to leave the company as of today," said spokeswoman Monica Talan.

Talan said she had no further information on the sudden departure.

Mackin could not be reached for comment.

Just last February, Univision announced that it had hired Mackin away from Hearst-Argyle Television, where he had managed the station group's Web and DTV initiatives.

Prior to that role, he had managed 14 of the Hearst-Argyle stations.

At Univision, Mackin was responsible for the company's 64 Spanish-language Univision and TeleFutura stations.
