The line graph delineates the evolution in the proportion of households owning four distinct electronic devices – MP3 players, mobile phones, computers, and tablets – over the period from 1995 to 2015.
Overall, mobile phones and computers exhibited a substantial upward trajectory, attaining near-saturation by 2015, while tablets, introduced later, saw a rapid surge. Conversely, MP3 players consistently remained the least prevalent, with a modest increase throughout the two decades.
In 1995, mobile phones were owned by a mere 10% of households, but this figure climbed dramatically to approximately 70% by 2000, subsequently reaching a peak of roughly 97% in 2015. Similarly, computer ownership, starting at 30% in 1995, rose steadily to 80% by 2015, though it never quite matched the ubiquity of mobile phones.
Tablets were virtually nonexistent until 2010, when they first appeared at 0%, yet they experienced an impressive surge to 30% by 2015. In contrast, MP3 players began at a minimal 0% in 1995 and increased gradually to 20% by 2015, significantly lagging behind the other devices throughout the entire period.
