(Sirius Subscribers article updated with information from CEO Mel Karmazin.)

NEW YORK ( TheStreet) -- Sirius XM Radio ( SIRI - Get Report) expects to end the year with the highest number of net subscribers in its history.

Chief executive officer Mel Karmazin announced that management expects approximately 20.1 million subscribers by the end of 2010.

This projection implies the company expects to add about 1.3 million subscribers in 2010.

>>Will Howard Stern Leave Sirius?

Karmazin made this announcement today at the Liberty Media conference. He said the total revenue for 2010 is expected to approach $2.8 billion, which would be up more than 10% from $2.53 billion in 2009.

In 2009, the Sirius subscriber base fell from 19 million to 18.8 million due to weak auto sales and difficult economic conditions.

While Karmazin did not specify if famous shock jock Howard Stern will stay at Sirius once his contract is up at the end of the year, he did say that Oprah Radio and Martha Stewart will remain on the air.

Subscribers can also expect some new programming including Rosie O'Donnel's new show, Glenn Beck, John Madden and Cooking with Emeril.

The satellite radio company plans to release its full subscriber count and financial results for the third quarter by early November 2010.
