In 1996, he produced the first Internet TV show on German TV,
netNite, for
ZDF. Starting 1998 he developed and produced the tri-medial show
netRadio (broadcast, audiostream and live-cam) for Bayern3 radio station of the
ARD/
Bayerischer Rundfunk. Therefore, he developed an early
Second-Screen application named URLPush. Along with the Radio and TV shows, Aigner published the
netNewsletter (). The newsletter served 23.000 subscribers. This netNewsletter - and the lack of a
Double opt-in feature in 1996 – led to the first decision relevant to
unsolicited commercial email from the federal supreme court of Germany
BGH. A subscriber had mistyped his email address.Meanwhile, the ruling has been defined even more precisely: "A newsletter that is the result of an editorial activity has both freedom of broadcasting and of expression, even if it contains advertisements". At the turn of millennium, he co-created the art project
Screenhouse, with artist
Markus Heinsdorff, where websites were projected onto a exterior surface of the
HypoVereinsbank headquarters in Munich. In the year 2000,
Endemol contracted Aigner's agency for the multimedia implementation of the first
Big Brother TV sequel in Germany. In the year 2001, Aigner obtained a part-licence for the radio frequency 92.4 MHz and began broadcasting on
FAZ Businessradio with the daily program
net.fm, focussed on new media. Recently, Aigner has been predominantly working on the TV-documentary series
PilotsEYE.tv. The actual 13 sequels show the fascination of flying through the eyes of the pilots. The viewer can enjoy the flight from the jump-seat's perspective by means six synchronized cameras in high definition. The program is broadcast in many countries, and sold on DVD and Blu-ray. ==Teaching==
