debit an account Fulfillment, in ad serving and billing, was a constant challenge. Overture asked advertisers, in effect, to give them their credit cards. “We ran it like an ATM,” says Meisel. “They gave us an amount of money and we debited their account.” As growth became exponential, Overture was running an order of magnitude more transactions than a credit card network. Every time an Internet user clicked on a link or ad on a SERP, it was an ad sales transaction. Overture’s bookkeeping was like keeping track not only of all the butterflies in the world but also of how many times they beat their wings. “We had to do it minute by minute,” says Meisel. “Credit card issuers only have to reconcile at the end of the month.” Question: 1. "Overture asked advertisers, in effect, to give them their credit cards." Who exactly is "them' and "their" refer to? 2. “They gave us an amount of money and we debited their account.” What does "debited their account" mean here?

Sometimes neither−nor both−is sufficient. One of the lessons I have learned is that even if you have the latest, greatest technology or the cleverest, most advantageous business model, sometimes neither of those is enough to ensure success. Sometimes neither−nor both−is sufficient. Even with such assets, the distinguishing factors in success are often management skill, flexibility, and the initiative that only leadership can elicit. No matter how powerful or capable the new technology is, it’s such human factors that make the difference. What does "Sometimes neither−nor both−is sufficient." mean here?

enforcement of market advantage Now around 78 percent of ad sales take place between publishers and advertisers (with some intermediaries) and not on online exchanges. By conducting business this way, each party must use its subjective judgment about how much a certain viewer seeing an ad in a certain place at a certain time is worth. Wherever there is subjective judgment, there inevitably is wishful thinking or the enforcement of market advantage. In a buyers’ market, it’s the buyers’ appraisal of value that prevails. Sellers may disagree; nevertheless, they tend to concede the point. That’s not evidence of the correctness of the bid as an estimation of value. What does "enforcement of market advantage" and "That’s not evidence of the correctness of the bid as an estimation of value." mean here?
