Default histograms

Hi this is lil. Never did this before! Question - Histograms bars always shared a side, and a number in the scale. Now in the last few years, they have started using a scale with a range, like: 0-4 5-9 10-14. Why? Where does 9 1/2 go? There is no longer any reason for the bars to be joined. Why did the text books change this?
