MARKET OPPORTUNITY: Adobe maintains a hard grip on the creative market with their ubiquitous Photoshop, InDesign, and Illustrator tools holding up to 90% share of the market. Available exclusively through Adobe's subscription model, Illustrator has little siginificant competition in the digital drawing tool market. WHO ARE WE TARGETING: This book targets new/beginning illustrators who are either adopting a digital tool for the first time, switching from an existing tool to Illustrator, or adding Illustrator know-how to existing Adobe knowledge. We assume our reader is not a full-time / professional illustrator, but needs a reference on the basics in order to create, review, or edit drawings.
