IFF is a very well-designed format. While it is not directly used anymore, variations on it still do: RIFF, which is little endian as opposed to IFF which is big endian, lives on in WAVs, AVIs, and other formats. AIFF, an Apple audio format; Even PNG and Apple's QuickTime container format (commonly known as MP4 these days) were inspired by IFF.
