HOME GROWN: Look for a boost in local programming on KOCE Channel 50, the county’s public TV station, if all goes according to plan. . . . Using a $300,000 grant from the local Harry and Grace Steele Foundation, the station is shooting pilots for three local series: one profiling the county’s movers and shakers, one profiling prominent families in county history and one examining the county’s future. . . . All that’s needed now are production underwriters, a spokeswoman says.
