Comcast's Broadcast TV and Regional Sports Network fees combined could add nearly $40 to a customer's monthly TV bill after next month's price hikes, all while Comcast advertises much lower prices than people actually pay.Comcast's advertised prices do not include the Broadcast TV or the Regional Sports Network fees even though these fees account for a large portion of customers' actual monthly bills.Comcast defends price hikesComcast said in the letter to town officials in Sandown that "rising programming costs, most notably for broadcast TV and sports, continue to be the biggest factors driving price increases.Comcast's statement on the price increases blamed the rising cost of video programming but said the overall increases are lower than the most recent inflation rate:TV networks and other video programmers continue to raise their prices, with broadcast television and sports being the biggest drivers of increases in customers' bills.We're continuing to work hard to manage these costs for our customers while investing in our broadband network to provide the best, most reliable Internet service in the country and to give our customers more low-cost choices in video and connectivity so they can find a package that fits their lifestyle and budget."
