After a brief and rudely interrupted stint at NBC’s Today last year, Jamie Horowitz is suiting up for Fox Sports. He joins the team in 2009 - Jamie Horowitzthe newly created post of President of Fox Sports National Networks. The former ESPN exec will oversee programming, marketing and scheduling for Fox Sports 1 and Fox Sports 2 and supervise management and development of original programming and day-to-day operations for Fox Sports 1’s news and studio programs.

Fox Sports also said today that Jeff Krolik, President of Fox Sports Regional Networks, will add oversight of Fox Deportes.

Horowitz established his TV sports cred during a long run at ESPN, most recently as VP Original Programming and Production from 2012 until last fall, when he left to take the helm of NBC’s morning show. He had an official December 1 start date as SVP and GM of Today, but NBC News chief Deborah Turness said in a mid-November memo that Horowitz was not the “right fit” and was out — effectively meaning he was let go before he started.

“Fox Sports 1 is the fastest-growing sports channel in the country, and we’ve seen about a 30% viewership increase overall, and 50% increase for live events, year over year,” said Eric Shanks, President and COO of Fox Sports. “That substantial growth has made it necessary to more clearly define our organizational structure so we’re better positioned for long-term success. Bringing an extremely creative executive like Jamie aboard to oversee our national cable channels ties everything together.”
