IMO it was the Internet. C and Pascal dominated till 1994, then Java books were everywhere. I loved TP5 (the manual was awesome) but dropped everything to learn Java which promised the world: write once, run everywhere and Internet applications! Woohoo. Then Perl and Javascript were on the scene. WIRED magazine! Very exciting times. Netscape Navigator Gold baby. Delphi was "Microsloth Windoze" not even on my radar.
