Apple was just a user and had nothing to do with the development:

they just thought it was cool to transcode MP3 to AAC or something like that.
AAC is a more modern and efficient codec than MP3. Apple chose it for iTunes Music Store downloads as it offered higher quality for a given bitrate than MP3 ISTR. Apple have also used it in preference to AC3 I think for iTunes video content.
It's a widespread codec - DAB+ uses it, Japan uses it for broadcast TV as does the UK and some other European countries have migrated to it for TV. HDMI AVRs sold in Japan have had bitstream AAC support - but this isn't common in North America and Europe, so decoding to PCM or transcoding to AC3 is the norm here.
