Calling Avago "virtually unknown" might have been too dismissive from my part.
But lets consider 2013. Avago had a revenue of $2.5bn, respectable, but that's not much when compared with Qualcomm's $24.9bn, less than Broadcom's $8.3bn, NXP's $4.8bn, and Freescale's $4.1bn.
In fact it seems that at least when it came to revenues, Avago was the smallest company on that list.
