The number of Compare the Meerkat adverts that air on television in one hour can vary significantly depending on the network and time slot. Typically, advertisers might air multiple spots within that hour, often ranging from 2 to 5 adverts. However, during peak viewing times or special events, this number could be higher. For the most accurate count, one would need to observe a specific channel during a specific hour.
Philo T. Farnsworth is credited in the USA as having invented the TV. There were too many people involved in the development of various aspects of the system, for it to be credited to one person. Farnsworth developed the image detector and the electronic scanning system similar to what we use today. The person who actually first sent moving pictures over radio waves, to the public was Scottish inventor, John Logie Baird. Although he proved the principle and usefulness of televion, his system was largely mechanical and bares little relationship to what we watch today.

It entirely depends. Since different models and technologies of television are not the same, they can vary greatly. Typically, LCDs using LED backlights are the most efficient, using around 40 watts for a 30" screen. LCDs using cold cathode, neon, and other backlights use a bit more, usually around 50-60 watts for a 30" screen. CRTs are less efficient, using a more formidable 100-240 watts for a 30" screen. Plasma is the least energy efficient of all, consuming a whopping 150-300 watts for a 30", although most are larger. a 42" can easily consume a kilowatt! Unfortunately, I have no data regarding DLPs, OLEDs, CMDs, or projectors, although I know OLEDs are supposed to be more efficient than LCDs.
Radio has survived because of its simplicity - a radio is cheap and easy to use. Radio has also always had the latest music on it, so it is great for listening to music, but internet and TV music stations have only recently appeared. Some people would also say that the quality of programmes is better than TV as the lack of an image means that good scripting is essential.
