  4. Hello,
    I have a doubt
    As per my knowledge, I know that RTB mechanism involves mainly 3 segments ie; DSP, AD exchange and SSp.

    But, one of my colleague told me that RTB purely works from DSP end. I objected with him that, it works from AD exchange only and it involves both SSP and DSP into AD exchange for serving creatives on inventory .

    Let me know ASAP weather, it runs from DSP or ADexchange?

    1. Hi Jaswanth,

      RTB is a technology which is used in programmatic buying and involves all the platform like exchanges, SSP or DSP. Your colleague is not completely wrong as he is trying to say with the respect of buying and RTB is the technology which helps in buying via DSP but just add to him that RTB helps in selling also not just buying. You can read RTB post once and let us know if you need detail clarity on it.
