Dennis Miller, Former Exec at Turner, in Venture Start-Up

Former entertainment executive Dennis Miller has co-founded a venture capital partnership, Spark Capital, to make early-stage investments in companies that take advantage of the build-out of broadband networks.

The firm, based in Cambridge, Mass., has raised $260 million for its first fund, which will invest in the convergence of the media, technology and entertainment industries.

Miller was a top executive at Turner Broadcasting System Inc. and Sony Pictures Entertainment before shifting his focus to media investments as managing director of Constellation Ventures, a unit of Bear Stearns Asset Management. The firm backed several cable channels, including TV One and College Sports Television.

His partners in Spark have specialties in consumer electronics, private equity and venture investing, telecommunications and computer and software technologies.
