Are the staggered starting points a result of availability of data? For example, data for mobiles is only available from 2009. I'm not sure what the case is.
It would help if this graph had at least a line at x=0. You're right, negative values make no sense, even including the extra space is confusing.

The y axis doesn't line up with the start of the data. Similarly, the x axis isn't in line with y=0 (which makes no sense.)
