East Tennessee Public Television is now East Tennessee PBS, reports the Knoxville News Sentinel. “To cover our large viewing area of more than 925,000 households in East Tennessee, we’ve added two broadcast towers over the years, which is why we have two sets of call letters: WKOP in Knoxville and WETP in Sneedville,” said Teresa James, ETPBS g.m. The station had been using the former name for more than 40 years.
