in the later 1920s the radio completely

changed from a bulky device to a nice

complex that are in wooden cabinets

the design of the radio changed and it

became easier to use the technology was

far more complex

later after about two more years in 1921

music that was broadcasted from a radio

became more and more popular

this radio was a huge advancement on how

the radio did work before

the design changed and it wasn't so

packed with things on it and it was

easier to use

1930s and 1940s

in 1930 as technology improved the radio

was becoming smaller and cheaper

the radio changed the size and price of

it because of the technology they were

developing

more families started to buy it because

1950s and 1960s

starting in the 1950s the radio started

to present national news

some stations started to develop

reputations for broadcasting from

different locations

for example from a hot air balloon or a

swimming pool

in the 1960s the Space Program brought

more advances to the integrated circuit

the radio then could fit inside of a

frame of eyeglasses or in a pair of

small earphones

the radio now changed to be put inside

of smaller speakers

in the 1960s the radio was popular from

the music that was played

the FM radio started to really expand

due to the approval of the technical

standards for the stereophonic radio

1970s and 1980s

it wasn't until 1978 that more people

were listening to the radio

this was happening due to the simple

change that made listening to music much

easier

people at that time discovered how to

change the simple internet to where you

can listen to every stations around the

world

around the 1980s the radio speakers grew

with size

the speakers projected better sound for

the music or speech that was played

through it

the radio now has a more clearly sound

1990s

during 1995 the radio's technology

became more complex and there were added

features that were attached

lights and controls were added and even

a screen to see what station you're on

the technology grew and the radio

features and technology changed

in 1999 the radio changed a bit by

adding a bigger screen and making the

radio more fancy there were added

buttons and knobs that added more

features to the radio

people now were discovering more complex

technology and the radio's prices were

reaching higher and higher

2000s

in 2015 there were very compact with

large screens and controls

it is complex and it is also locate

inside cars now

the radio change to now having clocks

and even now we can connect devices to

it and play music or take phone calls

the radio has changed due to the

technology they devolved

in 2016 people were coming up with lots

of ideas for making radios for cars and

swimming areas and different places like

that the radios kept on expanding and

were getting more popular due to the new

comings of them

in 2018 there are many different types

of radios

they all are very complex and new with

all sorts of controls

the radios have changed due to the

technology found and will continue to

change as more technology is devolved

today radio has become much more than

Tesla or Marconi could have ever

imagined

traditional radios and radio

broadcasting have become a thing of the

past

instead radio has steadily evolved to

keep up with current technology with

satellite and streaming internet

stations gaining popularity

radios are found not only in homes but

they are also a staple in vehicles

this was the evolution of the radio
