Microsoft and Intel, however, will also shed light on consumer spending patterns, most notably in the

under-pressure

PC market.

Intel recently lowered its

fourth-quarter revenue forecast

, citing weakness seen from the floods in Thailand. The tech bellwether, though, said that PC sales are expected to be up sequentially in the fourth quarter.

Internet giant Google is expected to report revenue of $8.407 billion and earnings of $10.49 a share after market close on Thursday. Google posted revenue of $8.44 billion and $8.75 a share in the same period last year.

As always, Google's Traffic Acquisition Costs, better known as TAC, will be a key number for investors. TAC is the amount of money that the search giant pays to other sites for their traffic, and came in at $2.07 billion, or 25% of advertising revenues, during the prior year's quarter.

Piper Jaffray analyst Gene Munster said that he expects Europe to be Google's "biggest wild card" for the fourth quarter, but notes that this should be offset by strength in the U.S. and the rest of the world.
