A streaming multimedia communication network includes a broadcaster providing program content by air wave or direct line to a network service provider, e.g. an Internet Radio Service provider (IRSP) which operates a web site for distribution of the content to remote end users over the network. The IRSP reformats the broadcast content into industry-standard streaming format, such as Real Audio. End users are coupled to the IRSP through a local network service provider, e.g. an Internet Service provider (ISP). An alternate content source is connected by airwaves or direct line to the ISP. The end user accesses the IRSP web site to select and receive program content over the network from a remote broadcaster listed on the site. The ISP transparently switches the network content at predefined intervals and substitute alternative content for the selected content during the predetermined interval for delivery of the alternative content to the end user.
