"The parallel ads technology enables us to show specific advertising as part of our internationalisation strategy and overseas marketing in target international markets. On the one hand, that could be a partner who wants to be active in those target markets. On the other, the system can also be used to promote international club activities," explained Markus Breglec, Chief Marketing & Innovation Officer at Bayer 04.
In the future there will be an international feed with parallel advertising in addition to the existing feed for the DACH target region. Bayer 04 has already gained the first partner for broadcasting advertising messages in international target markets.
The parallel ads technology from the provider TGI Sport works with image frequencies used in TV production. At defined intervals, the TV cameras record different images from the LED perimeter screens at the BayArena.
While the spectators at the stadium and the TV viewers at home in the DACH countries will not notice any difference, the image from the LED perimeter screens can be used for international viewers through the new technology in international broadcasting signals.
In 2019, Bayer 04 installed the LED perimeter screens at the BayArena so that they could potentially be used for the innovative parallel ads technology. Thanks to this new system, a very high quality of advertising is possible as the adjusted image is not virtually laid over the original but is directly played on the LED perimeter screens.

For the second time in four days, Bayer 04 face Borussia Dortmund this Tuesday evening, 2 December (kick-off: 21:00 CET) - this time in the round of 16 of the DFB Pokal, with more than 7,000 fans supporting the Werkself at Signal Iduna Park. After the recent 2-1 defeat to BVB in the league, several cup stats provide hope of revenge for the Black and Reds. There are several reasons why Bayer 04 recommends getting to the round of 16 clash early, in which VAR will be in use, unlike in the previous rounds.
