In this blog I will be discussing how entertainment has developed and improved over the past 100 or so years. When these technological advances started they were quite expensive to afford. This meant that only the rich or very wealthy people could afford these pieces of technology. This made early technology rare as the equipment used to make these forms of technology were not very efficient, so the prices of them were a lot. Below is an image of an entertainment timeline. This shows the different forms of entertainment and how entertainment has evolved over time.
1900-1949
The radio was first introduced in 1901. When the radio was first introduced not many people had them as they were too much for most people to afford, unlike today where everyone has one and they are a very common item. When radio was first introduced it worked through wireless telegraph. As science developed and electromagnetic waves were discovered, people found out that the electromagnetic waves are a much better way of transmitting through radio, so then radio started using these to transmit. The radio then went on to being installed in cars and has advanced through time. 
A second technological advance through this period was the development of theatre. This technological advance in theatre was the invention of drive-in theatres. This invention was made by Richard M. Hollingshead. In 1932, Richard M. Hollingshead of Camden, New Jersey created the first outdoor theatre by nailing several movie screens to trees in his backyard and placing a movie projector on the hood of a car. To determine if audio could be heard clearly in a vehicle, Hollingshead put a radio behind the screen to test the sound. He put ramps and blocks in his Thomas Avenue driveway to see how well cars could view the movie screens. In June, 1933, Hollingshead opened a drive-in movie theatre with a 40-by-50 foot screen in a lot big enough for 500 cars. In these times drive in theatres were extremely popular and seen as a major technological advance.
In 1940 the first digital computer was invented. These were originally the size of a large room and consumed as much power as several hundred personal computers (PC's). These computers were invented by John Vincent Atanasoff and Cliff Berry.
1950-1969
In 1958 the first video game was invented by William Higinbotham. This game is called Tennis for Two. Higinbotham invented this game to make science exhibits more interactive for the public. Higinbotham wrote, “it might liven up the place to have a game that people could play, and which would convey the message that our scientific endeavours have relevance for society." Tennis for Two uses a two dimensional side view of a tennis court, where the people playing the game has to knock the ball over the net and the first person to fail to achieve this and hits the net loses. Players served and volleyed using controllers with buttons and rotating dials to control the angle of an invisible tennis racquet’s swing.
In 1962 Phillips invented the compact cassette medium for audio storage. This was invented in the Netherlands. The compact cassette went on to be released in Europe in 1963 and in the US in 1964. The compact cassette was a huge technological advance within the music industry.
1970-1989
The main invention in this time period was the invention of the mobile or cellular phone. The cellular phone was invented by Martin Cooper in New York and was first released in Japan in 1973. Cooper invented the mobile phone while he was working for Motorola. The first mobile phone was released by Motorola and was called the DynaTac phone. The DynaTac was then released in America in 1983 with a price tag of $3995. Even though this was a very high price to pay there was a long waiting list and everybody wanted on as it was an extraordinary advance in technology at the time. In 1981 the first IBM computer was invented and was called the IBM PC (personal computer). The IBM PC was invented by a group of engineers and designers directed by Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida. The IBM PC was kept a complete secret until its release date in 1981. IBM paired with Bill Gates for the IBM PC, and Gates was responsible for constructing the operating system for the new IBM PC. This operating system was called MS-DOS 1.0. The starting price of the IBM PC was $1,500.
Later on that here Bill Gates went on to invent Microsoft. Microsoft was first invented ion 1986. Microsoft was established to develop and sell basic interpreters for the Altair 8800. Micorsoft is now the dominant software today and is making billions and pounds.
1990-2009
The World Wide Web (WWW) was invented in 1990 by Sir Tim Burners-Lee. Burners-Lee was a British engineer and computer scientist. Burner-Lee was the leader of the group of people who invented the World Wide Web as I have already stated, defined Hyper Text Markup Language (HTML) used to create webpages, Hyper Text Transfer Protocol (HTTP) and Universal Resource Locator's (URL). A second new invention in this time period was the iPod. Apple publicly announced the launch of the iPod in 2001. The iPod is a portable music digital player and was released just after the release of iTunes. The CEO of apple, Steve Jobs, ordered engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Jonathan Ive. The iPod was invented because another product like the iPod were found to be either big and clunky or small and useless by the workers at Apple, so they decided to release their own version which has become the most popular choice of portable music digital players today.
YouTube was invented in 2005 by Steve Chen, Chad Hurley and Jawed Karim. These three people sold YouTube to Google in November 2006 for $1.65 billion. Steve Chen, Chad Hurley and Jawed Karim were all employees at PayPal when they met. Hurley studied design at Indiana University of Pennsylvania, while Chen and Karim both studied computer science together at University of Illinois at Urbana-Champaign.
