NEW YORK (AP) — NBC boss Jeff Zucker will step down after cable provider Comcast takes control of the television programmer late this year.

Zucker, CEO of NBC Universal, informed employees of his planned departure in a Friday e-mail, and Comcast executives said they wished him well.

A possible change-in-command has been looming since last December when Comcast Corp. agreed to buy a 51 percent stake in NBC Universal from General Electric Co.

Zucker said in an e-mail to NBC Universal staff that leaving was a tough decision. He made his name at NBC as a youthful executive producer of the "Today" show, then became its entertainment chief. He has been moving up the corporate ladder even as NBC's entertainment unit has faded.
