On the road, television can be received by pocket sized televisions, recorded on tape or digital media players, or played back on wireless phones (mobile or "cell" phones) over a high-speed or "broadband" internet connection. Still, the 2000s saw a rise of several independent television networks such as REN (its coverage increased vastly allowing it to become a federal network), Petersburg Channel Five (overall the same), the relaunched 22. 30 September 1929: Baird begins regular experimental 30-line television broadcasts.
