Overall, the graph shows that there is much movement in the number of sales and rentals from 2002 until 2011. In particular DVD sales started to become highly popular and increased from approximately 48000 in 2002 up to 215000 in 2007, but then slowly decreased again. Meanwhile, VHS sales, with a number of 85000 in 2002, disappeared completely in 2006. Rentals experienced a similar retreat, but did not vanish completely. The only category in the graph that exhibits an upwards-trend is the Blue-ray that started its rise in 2007 and as of 2011 counts 15000 sales approximately. Finally, the visualized numbers reveal that Rentals ans VHS sales were at their peak at the beginning of the time-series. Their decline however developed differently; while rentals diminished slowly, VHS sales convey much higher negative growth. The biggest and smallest absolute growth rate was achieved by DVD sales and Blue-ray sales, respectively.
