Systems and methods are disclosed for automatically adding advertisements into a ticker. The disclosure includes receiving a request for a ticker data feed and generating a modified ticker data feed from the original data feed. One or more advertisements are selected and inserted as data items into the modified ticker data feed. The modified ticker data feed is then transmitted to the requester. When rendered on the requestor's device, the modified ticker data feed displays the data items of the originally requested data feed along with the advertisements in a scrolling ticker.
