There are more than 3,000,000 car radios in the Boston area. On March 24, though, many of these devices became quarantined along with their owners. That was the day when the Governor of Massachusetts shut down the state to slow the spread of COVID-19.

According to the Apple Mobility Index, the Governor's public-safety order caused traffic on Boston roadways to plummet to 50% of pre-pandemic levels.

By the beginning of July, however,  the AMI indicates that traffic in Boston began to exceed pre-Covid levels. The surge in mobility is due, in part, to work-from-home, furloughed, and laid-off employees returning to their workplaces.

According to Nielsen, during the week of April 30, only 39% of adults with jobs were working outside-the-home.  During the week of October 1, though, that number had expanded to 61%.

Before COVID-19, most listening to Boston radio happened outside the home. Consumers were tuning-in to their favorite stations from the car on the way to their job. Then, they tuned-in when they arrived at work. They listened again during the commute back home.

Nielsen recently surveyed consumers who worked from home before and during the novel coronavirus outbreak. The results show, as of June, 66% of respondents now work from home full-time as a consequence of the pandemic.

As consumers are compelled to work from their houses and curtail their commutes, the share of at-home listening to Boston radio has grown by 24%, according to Nielsen.

During July, Boston's 3,142,800 adult radio-listeners spent two hours per day listening to their favorite stations, according to Nielsen. Although local consumers had spent fewer minutes listening at the onset of the pandemic, the current time tuned-in remains unchanged compared to a year ago.

Some advertising experts had predicted that as consumers spent more time at home because of COVID-19 concerns, the hours devoted to radio listening would decrease. That, however, was not the case.

In July of 2019, according to Nielsen, 34.3% of radio listening occurred at home. During July of this year, in-home listening jumped to 42.6%. Despite the reduction in out-of-home activities, though, consumers still spent the exact amount of time listening to Boston radio.
