Is there an enlargement of IT players in the job market?

Question

Career in IT

I noticed that now, when looking at work as a back-end developer, about 7 out of 10 vacancies are some big players (integrators, large retail networks, some providers) who already have 30-50+ programmers in the states. And according to my personal feeling, this was not the case before, somehow there were more companies that did some kind of small services.
Did the IT business follow the "typical" path and began to grow larger?

Answer 1

Companies grow summit on their own, small ones most often just die, somehow they are lucky and they are bought

Answer 2

First, any company, in any industry, must always grow and develop. If a company stops developing, it quickly dies in the competition. The only exception is a local traditional business that works for a narrow group of regular customers. Secondly, the IT business has long followed this path, for example, IBM has been growing since 1924.
