Methods, apparatuses, systems, and arrangements enable the dynamic manipulation and utilization of electronic program guide (EPG) data. The EPG data can be dynamically manipulated and utilized while in a displayable format. In an exemplary implementation, EPG data is received from an external source, the received EPG data being in a displayable format. The received EPG data is added to previous EPG data to form current EPG data, the previous EPG data and the current EPG data being in the displayable format while the received EPG data and the previous EPG data are added together. At least a portion of the current EPG data is then displayed. In described implementation(s), the receiving, adding, and displaying are effectuated by a node that is coupled to a gateway in a local network system. The gateway may store and provide EPG data, and the local network may be operable in a television-based entertainment environment.
