The Bundeskartellamt, Germany's competition authority, has conducted a thorough evaluation of RTL's proposal to include RTL2's TV advertising space in its marketing efforts. This proposal aimed to enhance advertising opportunities for both channels.

After careful consideration, the authority has communicated to RTL and RTL2 that it does not see any potential for this cooperation to proceed. The decision reflects the authority's commitment to maintaining competitive practices in the advertising market.

This outcome underscores the regulatory scrutiny that collaborative marketing efforts face, particularly in sectors where competition is crucial for market health. The Bundeskartellamt's stance indicates a cautious approach to potential joint ventures that could impact market dynamics.
