Which advertising strategy would you like to do? is it offline or online strategy? Share your views. I prefer online advertising to be a better choice. Because if you reach out live, people may remember you. Else in offline advertising, we cannot see the immediate reactions of the public.
I think a mix of both is suitable, really. Though lots of people can and do access the Internet all over the world, many persons can't, so ignoring offline advertising is not a sound strategy from my perspective. When in doubt and if you can afford it, diversify your advertising strategy!
