it is clear that IT industry had a rose of a peak between the years 1996 and 2000. on the other hand service industry didnt really had a rise and was on a steady grow from 1992 to 2000.
if we take a look to the number of productions we can see that IT industry was on the top in the times that are shown while the service industry was always lower without any changes in the number of productions.
in the year of 2000 IT industry saw a high number of production which was two times larger than service industry production. service industry could not really reach to the IT industry even though it was the biggest rose of it in the period that is mentioned.
between the years 1994 to 1996 IT industry saw a negligble down in production which was nothing compared to the rise of it in several years. we can agree that service industry was succsesful in this field cuz it never saw a down and was always growing in year.
