San Francisco -- ON24, a San Francisco-based provider of webcasting and virtual event services, said on Tuesday it has acquired Spain-based Imaste, a provider of virtual events in Europe. Financial terms of the deal were not disclosed. The company said the acquisition -- its first ever -- will bolster its presence in Europe and Latin America, as well as enhance its position in the worldwide virtual events market.
