The primary reason NBC left WSVN was due to their preempting of NBC programming in the run up to the 1988 Olympics. WHDH famously wanted to air an hour of news in place of The Jay Leno Show before its debut and stated that Leno's 10pm show would hurt the 11:00 News. Although 'HDH was ultimately proven right, NBC pulled rank so-to speak and threatened to rip the affiliation from them and WHDH caved. As for NBC, reports have said that they've pretty much already started the groundwork for the new NBC Boston and other reports suggest that the new O&O will replace their current Telemundo O&O WNEU 60 , with Telemundo moving to 60.2 and will go into operation when the current contract with WHDH expires in 2016.
Back on topic. Ed Ansin Sunbeam owner(which owns WHDH Boston and WSVN Miami) spoke out to the Boston Globe. Seems NBC keeps trying to screw him over. Like they did back in Miami in the early 90s when NBC pulled its affiliate from WSVN and bought WTVJ and WSVN was forced to affiliate with FOX, hence the birth of the OTT tabloid format that Sunbeam perfected at WSVN and transplanted to WHDH Boston. The tabloid was WSVN's saving grace to keep viewers by turning their news product into "must see programming".
