Microsoft's Bill Gates told NBC's Tom Brokaw he does not think a deal with Yahoo was likely, CNBC reported on Friday. (Video: Gates and Brokaw discuss MSFT's past and future)
Microsoft had sought a tie-up with Yahoo for more than a year and by early May had offered up to $47.5 billion, or $33 per share, to buy the Internet company.
The software giant had hoped a Yahoo deal would accelerate its ability to capitalize on Web advertising growth and compete with Google , which is increasingly fighting for the same Internet audience.
Gates is retiring from Microsoft on Friday, although he will remain the company's non- executive chairman.
CNBC will preview segments of the Brokaw interview all day on Friday.
