The first commercial digital radio service launched in 1999 but take up of digital radios was initially slow.
However, the recent introduction of a £99 radio has helped double listeners in the last three months to about 150,000.
"It's important to keep the momentum going," said Ms Jowell, adding that manufacturers and retailers had to meet demand.
"More choice, lower prices, and the fast-growing programme range are giving digital radio, at last, the chance of really taking off," she added.
There are currently about 30 regional and local digital licences, offering 300 digital radio stations, with five digital-only radio channels from the BBC.
Of the BBC services, Ms Jowell said: "Some may still feel
that they invade competitive space, but I believe that they are genuinely distinctive."
The minister said she would be asking the BBC and Ofcom to canvass the views of the holders of all multiplex or
digital radio service licences.
"I am confident that digital radio
will prove a winner," she said.
