History of Telephone
Telephone is made with Satellites and Optical Fibre.With the help of Telephone People can stay in connect with each other with a talk.Though today there are Mobiles also.
In the Year 1950,there was only 1.7 lacs telephone connections but now its expanding.In the Year 2001,there were 2 lacs Local Telephone Booth (PCO) and more than 3-4 lacs STD booths in the whole country.Except some cities,the whole entire telephone service was managed by Bharat Sanchar Nigam Limited which is popularly known as BSNL.In this company BSNL,there are nearly 5 lacs employees working.So in this way Communication is expanding day by day.And no ones knows till how it will expand as everyday some new invention is done by someone.
