One result of the faster media cycle is the implications for corporate bottom lines. In the old days, everyone could say we have to wait for the offical report in 18 months' or so time. By then the story had vanished from media attention and possibly a majority of prospective pax would not even learn about the final report when it came out. The airline concerned received a commercial advantage or "breather" from this buffer.
However, the situation now seems different. Perhaps this is the first time in a heavy crash that the responsibilities seem so clearly attributed, so early on. This must be very worrying for Asiana, and hence their imploring NTSB to be more discreet with releases, and calling for everyone to wait until the final report is out. NTSB will need to weigh the hurt to airline bottom lines from the fast news cycle from just one bad flight, versus the advantages of the faster and freer media such as in forcing airlines to quickly undertake necessary (and perhaps other, cosmetic) system reforms in order to retain the confidence of the flying public.
