Scripps Networks has appointed Andy Singer, formerly the general manager of the company’s DIY Network, as head of programming and production at Travel Channel. Singer, whose new title is SVP Programming and Production Development, will focus on developing shows, talent and the network’s programming strategy; he replaces Fred Graver, who is focusing on special projects. Scripps is looking to grow Travel beyond its current 66 million households; earlier today, the company reported that the network’s revenue was up 15% year-over-year; Ross Babbitt will take Singer’s post at DIY. Before Scripps, Singer was a show producer at VH1 and also produced programs for A&E, 20th Century Fox, Fox News Channel, MSNBC and nationally syndicated broadcast series Extra and Inside Edition.
