Thanks, Jirka. Revenues for the first quarter increased 30% to $18.9 million, with gross margins, also improving to 87.1%. This marks our fourth consecutive quarter of revenue growth over 20% while generating positive EBITDA. We ended the quarter with 750,100 members, which keeps us on pace for our target revenue growth of 20% plus for the year, while maintaining profitability and positive cash flows. Beginning in October 2019, we experienced a shift in the initial plan selection for new members from 10% to 30% selecting the annual plan. Members on annual billing represent a core upsell opportunity for our $299 Premium live access annual plan, which we will now begin promoting more aggressively. Total member acquisition costs during the quarter were $7.6 million or 40% of revenues, which was improved from 52% of revenues in the year ago quarter. We did see some relief during the quarter on the pricing in the digital advertising market, which allowed us to bring our per customer acquisition costs in line with the prior year quarter at $68. We recently hired our new SVP of sales to build on the recent early traction in our member driven growth initiatives. She will be focused on growing our member Ambassador sales team to go after our sizable global market opportunity. Selling and operating expenses excluding marketing and member acquisition costs in the first quarter were $7 million or 37% of revenues, which improved from 47% of revenues in the year ago quarter. Corporate and G&A expenses in the first quarter were 1.5 million in line with the year ago quarter. EBITDA improved to $3.5 million or 19% of revenues in the quarter from negative 0.2 million or negative 2% of revenues in the year ago quarter. This marks our fourth consecutive quarter of generating positive EBITDA and puts us on an annualized EBITDA run rate of $14 plus million, which is almost double the full year 2020 EBITDA, which we generated net income of $0.4 million or $0.02 per share during the first quarter of 2021, which is an improvement of $4 million from a net loss of $3.6 million or $0.19 a share in the prior year quarter. This increase reflects the fact that most of the incremental gross profit generated in the first quarter of 2021 compared to the prior year quarter flowed through to net income. Cash flow from operations increased to $5.2 million during the quarter and improvement of $3.2 million from Q1 2020 and our sixth consecutive quarter of generating cash flows from operations. We increased our content investment during the quarter as planned, while also increasing our overall cash balance to $13 million. With 80% of our monthly viewership going to our original programming, and our end to end content production fully in house, we have been able to control the cost on a per hour basis to ensure that our new content is providing a high return on investment, given our current member levels.
With the significant improvements we have made in our operational performance over the past two years, and the financial stability we have created with the sale of a portion of our corporate campus in September 2020 and the predictability of our cash flows going forward.
Our board has authorized a 5 million share repurchase program, as announced in our earnings release we filed this afternoon. This will provide flexibility as we look to optimize return on shareholder capital, as we continue to focus on growing revenues, operating margins and cash flows. With that, I would like to open up the call for questions. Operator?
