Depends on your perspective. Prices dropped significantly because people started to prefer dollars to some extent. Several of the large exchanges that existed back then are still around, however, and others were acquired. Examples of those still around: Coinbase, Bitstamp, Bitfinex, Kraken. Sure I'm missing others.

I mention the above only to say it didn't feel like a true bank run to me at the time. People were still able to get in and out, but prices were certainly depressed. And several of the exchanges survived.
