Sabbagh worked as a city reporter at The Daily Telegraph and as senior reporter on the magazine Computing before joining The Times where he was telecoms correspondent and then media editor between 2004 and 2009, when he resigned. In April 2005, along with his then editor Robert Thomson, he was served with a criminal libel summons from a French court by the Barclay Brothers over an article published in The Times in November 2004. That action was eventually dropped, and The Times published a statement in February 2007.
Sabbagh was co-founder of the media news and entertainment website Beehive City, along with two former Times colleagues Adam Sherwin and Timothy Glanfield, and was a contributor prior to joining The Guardian.
He was a Labour councillor for Vassall ward in the London Borough of Lambeth between August 1999 and May 2006. In 2010, he was media advisor to Oona King on her unsuccessful attempt to become the London Labour Mayoral candidate.
