AEG's entertainment industry expert, Eric Briggs, was back on the witness Monday. Briggs says Jackson may have sold out 50 concerts in London.
But he says commercial sponsors were less than enthusiastic to the idea of having Jackson endorse any of their products.
Briggs also says there was little chance of a follow-up concert in Las Vegas after the London tour.
Monday marks the beginning of the 14th week of the wrongful death trial filed by Katherine Jackson, Michael's mother, against AEG.
Potential witnesses for this week include Debbie Rowe and Randy and Rebbie Jackson.
