WSVN, no surprise really, chose to go it alone. They have been on non-stop since very early Friday morning re-broadcasting their sister station WHDH in Boston until little after 6am Friday morning when the WSVN team picked up and used their own reporters during the day. Interestingly they also aired some WCVB (
NBC ABC affiliate owned by Hearst) video on and off. WSVN reporter Kevin Ozebek and photojournalist Augie Conte who were dispatched to Boston right after the bombings have also been live from the scene all day as well.
WHDH had exclusive video available and its reporters got some great interviews and information out and as the event was unfolding early in the night CNN International relied on them and WCVB for coverage.
Nationally it seems, at least going by tweets, NBC is getting the most praise from people for having a measured, well rounded coverage. That in light of the wrong information that was disseminated by CNN and FOX.
