In the beginning days of the telephone 'Ahoy hoy' was the standard greeting when one answered the phone. It was later replaced by 'hello' and then 'who dis?'. Mr Burns revived this old greeting in the Simpsons.

Ahoy hoy was previously a term to greet or get the attention of small sloop-rigged coasting ship or a heavy barge used for freight.
Ahoy = Hello (in Dutch)
Hoy = A small sloop-rigged coasting ship or a heavy barge used for freight
In the 1870's, inventor and Scottish born Alexander Graham Bell invented the telephone. Bell's preferred salutation, Ahoy-hoy was derived from the nautical term above.
It really gained popularity when Mr. Burns used it on the Simpsons a few seasons ago, but the internet has adapted it for use as a common greeting. It's commonly spelled Ahoi hoi online.
