What is the expected revenue for the mobile business and the expansion of use cases in 2021-Q1 
e to make those investments in people and in technology to grow that. And then the mobile business will continue to do very, very well. If you look at where we see the market, we continue to see new content opportunities that we chase and variably win. We've got a China position now that I think is going to inflect higher as the content there on a relative basis is still lower than it is in other markets.
So, there's a great opportunity to move. And then the expansion of use cases. So, it's customers and use cases that we just haven't seen. Some of that came through the pandemic, a difficult period of time.
And some of that were technologies that just emerged. You think about Zoom, you think about Peloton, store-to-door delivery to your house, touchless payments, all of this stuff is not going to go away. It's not going to go away. But it's also going to be powered by connectivity.
It's going to be connected by the kind of things that we offer, again, whether it's WiFi, whether it's 5G, whether it's Bluetooth. I mean so there's a parallel market here that is building and creating unique momentum. I'm incredibly excited about the 35% broad market number in a period of time that typically was all about mobile. So, we're really demonstrating the ability to create diversification but still, in many cases, use common technology cores that run through our factories.
Craig Ellis -- B.Riley Securities -- Analyst
That's really helpful. It's pretty amazing to think that by late this year, those two businesses could be annualizing at $5 billion and $1.5 billion each. But my follow-up really is for you and Kris, on the share buyback. So, nice to see the $2 billion buyback.
The question is this, with $700 million remaining on the existing buyback, can you just give us some color on -- on why now with the new authorization? And what was it that dictated the $2 billion was the right amount versus, say, $1 billion or $1.5 billion or even $2.5 billion to $3 billion?
Kris Sennesael -- Chief Financial Officer
Yeah, it's very simple. The time expired on the prior authorization. It's a $2 billion program for two years. So that previous plan was put in place in January 2019 and expired in January 2021.
And so, we are putting in place a new $2 billion program covering the next two years.
