Around the mid 1990′s the advertising industry started casting lighter voices and regional accents. Out went the traditional RP and mid Atlantic accents, and in came the boy or girl next door.This opened up the door for comedians, actors and personalities with Dublin and rural accents to break into voice over land.Was it a good thing?

Yes, if the script requires a deep resonant voice, make sure you get your casting right, if your script requires the boy or girl next door with a light regional accent, the same rules apply.
