I used to to mostly advertising pieces, newspaper and magazine ads, street banners, billboards of various sizes and shapes, flyers and brochures, stickers, etc. With ads easily reaching 50% or more of the total.
The type of jobs is more varied there days. Probably comes with the change of territory. Now, most of my jobs are web-related: Web design/redesign, maintenance and fixes, PHP/MySQL, e-commerce. But I still get newspaper/magazine redesign jobs, corporate newsletters and the like.
