General Atlantic-backed ProSieben, a European mass media company, based in Germany, acquired eHarmony, a US online dating site. Terms were not disclosed. The transaction follows through on ProSieben’s push to diversify away from its core commercial TV franchise, where ad revenues are flat and the sector is being disrupted by streaming platforms like Netflix. The Munich-based broadcaster bought eharmony via its newly created Nucom division, in which investor General Atlantic took a 24.9 percent stake in February of 2018.
