Top music industry and digital media analyst Mark Mulligan is leaving Forrester Research after 11 years. No reason was given for his departure. "I’m taking a little bit of time out before making my next move," he said in an email. Mulligan had begun his tenure as an analyst with Jupiter Research which was acquired by Forrester in July of 2008.

"In the meantime I’ll still be blogging on music industry stuff over at my MusicIndustryBlog and basically making a nuisance of myself as an independent voice," wrote Mulligan who tweets as @Mark_Mulligan.
