Ian Valentine has joined GSN as senior vice president of programming.
The Emmy Award-winner had held the same title at Sci Fi Channel.
In his new role, Valentine will oversee GSN's production, development, acquisitions and program planning, managing the network’s programming staff, as well as its casting and production departments.
"Ian brings two decades of experience to his new position as GSN programming chief, including six years in key programming positions at basic-cable networks, three years in broadcast programming and six years as an agent," GSN CEO Rich Cronin said in a prepared statement.
GSN is in some 54 million homes.
