Measuring audience research- LO4 and LO5 recap

One trend of the graph is that from 2011 to 2020, the amount of 25+ adults has increased over time so more adults are listening to the radio on their phones and tablets. I think this happened because more mobile devices were released over the 9 years so there is more opportunity to play the radio as there is more devices 

Also, the peak for people aged 15-24 that listened to the radio on tablets and phones happened in 2016. This could be because some of the most popular songs were released in 2016 and maybe there were more devices sold in 2016.

Finally, the amount of all adults that listened to the radio on their tablets and phones gradually increased over time from 8% in 2011 to its peak at 28% in 2019. This could be because more people bought devices meaning more people are likely to have the radio on.
