Mobile television is television (TV) watched on a small handheld or mobile device, typically developed for that purpose. It includes services delivered via mobile phone networks, received free-to-air via terrestrial television stations, or via satellite broadcast. Regular broadcast standards or special mobile TV transmission formats can be used. Additional features may include downloading TV programs and podcasts from the Internet and storing programming for later viewing. Except in South Korea, consumer acceptance of broadcast mobile TV was limited due to a lack of compatible devices. [1]
Early mobile TV receivers were based on analog television systems. These models were the earliest televisions that could be placed in a coat pocket. The first was the Panasonic IC TV MODEL TR-001, introduced in 1970. The second was the Microvision or the MTV-1, and was also the first television that could pick up signals in multiple countries. The project took over ten years to develop and was funded by around £1.6 million in British government grants. [2] [3] Later products used 2G and 3G cellular technology as well as digital TV spectrum. [4] [5] [6]
In the 2010s, specialized mobile TV platforms and protocols were discontinued worldwide due to the rapid deployment of LTE cellular networks and the growing popularity of streaming television over the internet on modern smartphones. [7] [8] [9] [10]

Mobile TV services were launched in Hong Kong in 2006 by the operator CSL on the 3G network. [5]
