The experimental data on the processes pi pi -> pi pi, K (K) over bar, eta eta, eta eta' in the I(G)J(PC) = 0(+)0(++) channel have been jointly analyzed to study the status and nature of the f(0). The method of analysis is based on analyticity and unitarity and uses an uniformization procedure. Some spectroscopic implications from results of the analysis are discussed.
