The market is transforming from being one-sided to being two-sided. Thus in this article, we focus on integrating the business model concept with value co-creation with respect to the emergence of two-sided markets and intermediaries. As the transformation from a one-sided to a two-sided market and the birth of intermediaries bring forth value co-creation possibilities, this article aims to find out how value can be co-created in different mobile service production and provision models.1 aJärvi, Kati1 aPellinen, Antti  uhttp://timreview.ca/article/425
