I want to know the answer to the following question:
What is the sister station to WBZ-TV?
All the background I'm provided with is that "The city is served by stations representing every major American network, including WBZ-TV and its sister station WSBK-TV (the former a CBS O&O, the latter an MyNetwork TV affiliate), WCVB-TV (ABC),". Is that enough to answer the question?
Answer: yes
