C.V. Raman's Death Anniversary

 

C. V. Raman, passed away on 21 November 1970, was an Indian physicist born in the former Madras Province in India (presently the state of Tamil Nadu), who carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel Prize for Physics and was the first person in Asia to obtain said award for achievements in science. He discovered that when light traverses a transparent material, some of the deflected light changes wavelength and amplitude. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In the year 1954, the Indian government honoured him with India's highest civilian award, the Bharat Ratna.


World Television Day


World Television Day is celebrated annually on November 21 to draw attention to the influence of television on people and society. The UN General Assembly set this observance in December 1996 in honour of the first World Television Forum that happened on November 21-22, 1996.

World Television Day: History And Evolution

Television has gone through so many changes since its invention. The journey started with Black and White (B&W) Television in the early 20th century and offered very restricted programme viewing to the audience. Television was invented by Philo Farnsworth and the first public demonstration was in 1927.

The commercial production of B&W television sets began in the late 1930s.

Shortly, towards the 1950s, colour television was introduced, changing viewers’ experience as well as interest.

New technology in the early 1980s led to increased cable television programmes and channels that aired programmes that met the criteria of a certain section of society. This period also marked the arrival of satellite television, thus increasing accessibility.

After what can be described as the generation of digital television, introduced in the late 1990s, another set of advancements in technology formed the foundation of high-definition broadcasting in the early 2000s.

Today, smart TVs include internet connectivity, providing streaming and other interactive applications. Such changes are typical of advanced technologies, determining not only the type of content but also the audiences’ approach.
