Charles Cooper, executive editor of commentary at CNET, has written an article on the states of affairs between Apple and RealNetworks. Last week Real announced Harmony, which allows songs purchased through its online music store to be played on iPods, and Apple was not impressed. ” A history of bad blood between Steve Jobs and Rob Glaser, his opposite number at RealNetworks, no doubt plays into this developing novella,” writes Cooper. “But ego takes a back seat to a bigger consideration: power. Apple would like nothing better than to exert Microsoft-like domination of the music business.”
