GIF89a was the industry standard. Supported 256 colors, interlacing, transparency, and animation loops. File sizes were strictly kept under 15KB for 28.8k modems.

Art Techniques

Pixel-perfect dithering, custom color palettes, anti-aliasing hacks, frame-by-frame animation, and HTML table padding for layout. Created in Deluxe Paint, GifBuilder, and PhotoShop 3.0.

Delivery & Tracking

Server-side impression tracking via 1×1 pixel GIFs. Click-throughs used CGI redirects. No JavaScript tracking existed yet; everything was image-based and HTTP/1.0 compatible.
