When Wilmington, Delaware's first radio station, WDEL, began broadcasting on July 22, 1922, the station needed a tall antenna and lots of buried copper cable to transmit its signal.  Radio receivers at the time were mostly homemade and involved a piece of crystalline mineral and a wire coil.

Over many decades in Wilmington, both the broadcasting and receiving equipment improved. In the mid-1920s this meant store-bought radios. In the 1930s this meant car radios. In the 1960s this meant transistor radios. In the 1970s this meant boom boxes. And, in the 1980s this meant Walkmen. But, despite these improvements, the fundamental technology of big towers sending a signal through the air to a radio receiver remained the same.

In 1994, there was a new way for Wilmington consumers to listen to the radio. That was the year local stations across the country began streaming their signals over the internet and listeners could use their computers (later their smartphones and smart speakers) as receiving devices. No big antennas, no wires, and no actual radio needed.

In 2021, according to Nielsen, Wilmington radio reaches more local consumers than any other advertising media option.

Neilsen finds, too, that 34.4% of all consumers who listen to a Wilmington radio station over-the-air will, at some point during the month, also connect to a local station via the internet. 

According to Nielsen, 548,000 adults in the Wilmington, Delaware area have access to the internet, equivalent to 96% of the population. On average, local consumers are spending 10.59 hours per week online.

Wilmington millennials, the first generation that grew up in a digital world, spend considerably more time online. Nielsen reports that, on average, Wilmington's 25-39-year-old consumers are clocking 11.56 hours connected to the internet.

So, how are Wilmington consumers spending their time online?

According to Nielsen, streaming audio and video content, social networking, checking the weather, and banking are the top online activities for Wilmington consumers each month.
