In the radio industry Maggs co-presented SAfm's weekday afternoon current affairs programme, PM Live, as well as being the host of the Sunday morning media and advertising show, Media @ SAFM which focused on the advertising and communications industry. The program ran for 10 years - a show he refers to as his "great joy".

He also hosted SABC3's weekly media and advertising show, Media Focus.
He left the SABC in April 2008 to join the e-news channel.

Having studied Journalism at the then Natal Technikon, Maggs began a career in journalism writing for such publications as the Eastern Province Herald and Durban's Sunday Tribune. He still writes an irreverent weekly column for The Herald called 'Daze of My Life'.

His first radio job was at 702 where he stayed for 10 years, becoming the station's news editor and a regular current affairs anchor - at one point in a spicily memorable breakfast show partnership with 702's Jenny Crwys-Williams – with a reputation as a tough interviewer.

During his time there, amongst other things, he broke the story of Chris Hani's assassination and co-hosted a live rolling news programme on the day that Princess Diana died.

More recently, Jeremy was instrumental in developing the Eyewitness News brand on 702.

He left 702 to present the new SABC2 morning breakfast show (precursor to the present Morning Live), which he co-hosted.

This led to an invitation to present Media @ SAFM and then to PM Live - a show he refers to as his "great joy".

In February 2008 it was announced by e.tv that Maggs would be one of the co-anchors of the e.Sat pay channel's 24-hour news programme.

Until recently Maggs was also the advertising and media writer on the Financial Mail and was responsible for the authoritative yearly industry review called Ad Focus. He now publishes his own hardcover review of the industry called The Annual.

He is also the editor of the Journal of Marketing – the official publication of the Marketing Association of South Africa (MASA).

Currently Jeremy co-anchors the Primetime News Night daily on DStv's eNews Channel – this show includes interviews with news makers and spoke persons of organisations in the news

Jeremy is a seasoned  MC and a regular keynote speaker. His two main presentations are on “How to Ask Tough Questions” based on his nightly grilling of newsmakers and “Exercising Influence” in the corporate world.
