New Date for Thunder Day 2020

Thunder Day 2020 is coming – but a little later than originally planned. We have decided to move Thunder Day to the 8th and 9th October 2020 due to current developments with the spread of Coronavirus (Covid-19).

The team did not reach this decision lightly as developments regarding the spread of coronavirus are difficult to grasp. Many companies have already responded in the previous weeks and, for example, limited the business trips of their employees; conferences, trade shows and sporting events are being cancelled. This shows just how critical the situation is.

“We have been busy with this matter for days and have tried to look at the developments as objectively as possible”, explains Kai Riecke, CTO of Burda Magazine Holding and organiser of Thunder Day. “As part of our decision we have considered the rather fraught enquiries from speakers, guests and sponsors as well as the first cancellations from participants.”

From the Thunder Team’s point of view this decision was ultimately unavoidable. Thunder Day is a networking and community event – it lives from the interaction, closeness and knowledge exchange between participants. “We like to bring experts from our sector together and find solutions together for the publishing industry of tomorrow. And that only works when those involved are completely immersed. Thunder Day is only fun and worthwhile under such circumstances”, says Kai.

It was important to the Thunder Team not to cancel Thunder Day 2020, they wanted to postpone it instead – and in doing so ease as much pressure on the participants as possible. We are assuming that the situation will be clearer by summer as there should be more insight into the virus and its spread by then. “We should all feel a little more certain by then, one way or another, and can adapt to the situation accordingly”, assures Kai.

The new dates:

When? 8th and 9th October 2020

Where? MACE, Beta Straße 10F, 85774 Unterföhring

We hope that participants and speakers are able to understand our decision and look forward to getting together this Autumn in a somewhat more relaxed atmosphere.

Coalition Members develop valuable modules, using them for their own purpose and sharing them with the community under the GNU General Public License. The Coalition discusses feature requests and offers, celebrates new launches, and is a platform for programmers and executives in the publishing industry.
