Today, NBC confirmed the months long rumors that they would part with WHDH, Boston’s Channel 7 despite a decades long complicated relationship with the owner Ed Ansin’s Sunbeam Television Corp. (The relationship is so complicated, there will be 3 different posts; this one about the local; the other just on Sunbeam/NBC and NBC’s other victims.) The relationship is expected to end by this calendar year and by January 1st, NBC will be on another TV station. Both newspapers as well as competing stations had reports on Thursday. If the local mass media is reporting this; then this really may develop in a once in a lifetime media biz drama.
