The difference in strengths between Photoshop and Illustrator became clear with the rise of the Internet, Illustrator was enhanced to support Web publishing, rasterization previewing, PDF, and SVG (Scalable Vector Graphics.) Adobe was an early developer of SVG for the web and Illustrator exported SVG files via the SVG File Format plugin. Using the Adobe SVG Viewer (ASV), introduced in 2000, allowed users to view SVG images in most major browsers until it was discontinued in 2009. Native support for SVG was not complete in all major browsers until Internet Explorer 9 in 2011.
