NEW YORK (AP) — HGTV is working the buddy system. The home-and-garden network has upped the number of shows with co-hosts who are related or married to five, adding "America's Most Desperate Kitchens," hosted by cousins Anthony Carrino and John Colaneri, to its lineup of shows hosted by spouses, siblings and other assorted relatives. Keeping it all in the family is deliberate: "The natural conversation and exchanges between them as experts with a pre-existing relationship engages audiences," said HGTV general manager Allison Page. The lifestyle network's top show "Brother vs Brother," starring brothers Drew and Jonathan Scott fixing houses for resale, averaged 2.5 million viewers this season — a 47 percent increase over last year's viewership, according to Nielsen ratings. Carrino and Colaneri are back with their fourth HGTV show this summer.Read more on NewsOK.com
