Google Inc. and General Electric Co.’s NBC Universal said they have abandoned a television advertising-sales partnership that began two years ago.

“We’re not currently contributing inventory into the Google marketplace,” NBC Universal spokeswoman Liz Fischer said in an e-mailed statement.

A Google rep confirmed that the companies are ending the arrangement.

NBC Universal struck a deal with Google in September 2008 for the Internet-search provider to broker ads for cable networks including MSNBC, CNBC, SyFy and Oxygen. Google allowed customers to buy TV spots using its self-service Web site, and the NBC agreement bolstered the program that previously only worked with Dish Network Corp.

NBC and Google split the revenue and collaborated on marketing and research.
